TL;DR: Scores on the corresponding scales for the five needs did not correlate significantly and positively, except for the measures of physiological needs, and there was limited support for Maslow's hypothesis that need deprivation would predict psychopathology.
Abstract: Two scales have been proposed to measure Maslow's hierarchy of needs in college students, one by Lester (1990) and one by Strong and Fiebert (1987). In a sample of 51 college students, scores on the corresponding scales for the five needs did not correlate significantly and positively, except for the measures of physiological needs. Furthermore, there was limited support for Maslow's hypothesis that need deprivation would predict psychopathology (specifically, mania and depression).

TL;DR: Bi-factor analysis was used to demonstrate the presence of a very strong general factor and, in comparison, two weak group factors of the Utrecht Work Engagement Scale, and shed additional light on the meaning of the work engagement construct.
Abstract: Despite wide-spread use, questions remain about the dimensionality of the 9-item Utrecht Work Engagement Scale (UWES-9). Theoretical underpinnings of the UWES-9 point toward a hierarchical structure with a general factor and three group or primary factors: Dedication, Vigor, and Absorption. To date, researchers have failed to model the general factor, which contributes to the lack of consensus about the dimensionality of the scale. Bi-factor analysis was used to demonstrate the presence of a very strong general factor and, in comparison, two weak group factors. The results shed additional light on the meaning of the work engagement construct. The implications for research with the UWES-9 are discussed.

TL;DR: The experiments described in this paper show how purposeful behavior can appear to be caused by the independent variable when an organism's purposes are ignored and show how taking purpose into account using the control theory-based “Test for the Controlled Variable” can provide a productive new methodological direction for experimental research in psychology.
Abstract: Summary—Experimental research in psychology is based on a causal model—the General Linear Model (GLM)—that assumes behavior has causes but not purposes Powers (1978) used a control theory analysis to show that the results of psychological experiments based on such a model can be misleading if the organisms being studied are purposeful (control) systems In the same paper, Powers presented evidence that organisms are such systems Nevertheless, psychologists continue to use methods that ignore purpose because the behavior in most experiments appears to be non-purposeful (a caused result of variations in the independent variable) The experiments described in this paper show how purposeful behavior can appear to be caused by the independent variable when an organism's purposes are ignored The results show how taking purpose into account using the control theory-based “Test for the Controlled Variable” can provide a productive new methodological direction for experimental research in psychology

TL;DR: Results indicated that sleep duration correlated negatively with verbal aggression, physical aggression, and anger and shorter sleep duration was a significant predictor of verbal aggression and anger.
Abstract: Evening orientation and sleep duration have been linked with aggression and problematic behaviors, but no study has used an explicit aggression questionnaire. The present study used the Buss-Perry Aggression Questionnaire based on physical aggression, verbal aggression, anger, and hostility, as well as questionnaires on the timing of sleep and sleep duration to assess this relationship in young adult men. The Composite Scale of Morningness was used to assess circadian preference; sleep-wake variables (wake time and sleep onset time on weekdays and on weekend days) were used to calculate midpoint of sleep, social jetlag, and sleep duration. Results indicated that sleep duration correlated negatively with verbal aggression, physical aggression, and anger. Short sleepers were more aggressive. Using multivariate analysis of variance, shorter sleep duration was a significant predictor of verbal aggression and anger. Concerning physical aggression, social jetlag also contributed to the model. Morningness-eveningness was associated with the hostility scale with eveningness related to higher hostility. Men scored higher than women in physical and verbal aggression.

TL;DR: The result suggested that social network sites cannot improve highly anxiously attached individuals' social capital effectively; they may need more face-to-face communications.
Abstract: This study examined the moderating role of attachment anxiety on the relationship between intensity of social network site use and bridging, bonding, and maintained social capital. Data from 322 undergraduate Chinese students were collected. Hierarchical regression analyses showed positive relationships between online intensity of social network site use and the three types of social capital. Moreover, attachment anxiety moderated the effect of intensity of social network site use on social capital. Specifically, for students with lower attachment anxiety, the relationships between intensity of social network site use and bonding and bridging social capital were stronger than those with higher attachment anxiety. The result suggested that social network sites cannot improve highly anxiously attached individuals' social capital effectively; they may need more face-to-face communications.

TL;DR: Using the Index of Sojourner Social Support Scale, international students reported perceiving greater socioemotional and instrumental support from other international people than from Americans.
Abstract: This study investigated the extent and sources of perceived social support among international students attending a northeastern university in the United States. Using the Index of Sojourner Social Support Scale, international students reported perceiving greater socioemotional and instrumental support from other international people than from Americans. Results also indicated that younger international students perceived more socioemotional and instrumental support from others than did older international students. The findings point to sources of social support available to international students in the host culture and the important role such types of social support may play in helping international students make adjustments to living and studying in a new cultural context.

TL;DR: This study explored the relations between use of the social networking site Facebook and scores on affinity-seeking, social loneliness, and social avoidance by 313 college students, with men having significantly more embarrassing content than women.
Abstract: This study explored the relations between use of the social networking site Facebook and scores on affinity-seeking, social loneliness, and social avoidance by 313 college students. Social loneliness and social avoidance, but not affinity-seeking, were positively and statistically significantly related to time spent using Facebook. The number of close Facebook friends was negatively and statistically significantly related to social loneliness and social avoidance. Women perceived Facebook as a more integral part of daily interactions than did men. 38% of the 283 Facebook members indicated their accounts contained information and/or a picture that could embarrass them, with men having significantly more embarrassing content than women. The findings are discussed within the context of social compensation.

TL;DR: Results suggest that the FDUREL is a reliable and valid measure of religiosity in Farsispeaking populations and had good internal consistency and test-retest reliability.
Abstract: This study examined the validation and reliability of the Farsi version of the Duke University Religion Index (FDUREL), a brief measure designed to evaluate the primary dimensions of religiosity. The study was conducted in two phases. In the first phase, after translation of the original version of DUREL by using standard forward-backward translation, the FDUREL was administered to 427 medical students at different training levels. Reliability of the FDUREL was assessed by internal consistency and test-retest reliability. Principal components factor analysis was employed to assess the construct validity of the measure. In the second phase, 557 medical students were asked to fill out the FDUREL and Hoge Intrinsic Religiosity Scale to examine concurrent validity. The FDUREL was unidimensional and had good internal consistency and test-retest reliability. Results suggest that the FDUREL is a reliable and valid measure of religiosity in Farsi-speaking populations.

TL;DR: The Japanese RRS was shown to be a reliable and valid measure that has the potential to contribute to future depression research and clinical practice and correlational analyses indicated that Brooding, rather than Reflection, assessed maladaptive aspects of rumination.
Abstract: The Ruminative Responses Scale (RRS) is a measure of depressive rumination and, although several versions have been developed, the version by Treynor and colleagues has been used most frequently in research. This version contains two subscales: Brooding and Reflection. In the present study, the 22-item RRS was translated into Japanese and psychometric properties of the measure were examined in two samples of Japanese undergraduate students (ns = 299 and 56). Confirmatory factor analysis indicated that a two-factor model of the RRS showed a moderate to good fit to the data. The total and subscale scores indicated adequate reliability and construct validity. Consistent with previous studies, correlational analyses indicated that Brooding, rather than Reflection, assessed maladaptive aspects of rumination. The Japanese RRS was shown to be a reliable and valid measure that has the potential to contribute to future depression research and clinical practice.

TL;DR: Convergent validity was confirmed as the Greek MBSRQ–AS subscales correlated positively with the ASI–R and the SATAQ–3 and the psychometric properties of a Greek version of the Multidimensional Body-Self Relations Questionnaire–Appearance Scales were studied.
Abstract: The psychometric properties of a Greek version of the Multidimensional Body-Self Relations Questionnaire-Appearance Scales (MBSRQ-AS) were studied. A total of 1,312 high school students (463 boys, 849 girls) were administered the Greek MBSRQ-AS, the Greek Appearance Schemas Inventory-Revised (ASI-R) and the Greek Sociocultural Attitudes Towards Appearance Questionnaire-3 (SATAQ-3). An exploratory factor analysis revealed that the Greek MBSRQ-AS items significantly loaded with the scale's main factors. Internal consistencies of the subscales ranged from .76 to .86. Test-retest reliabilities ranged from .75 to .93. Convergent validity was also confirmed as the Greek MBSRQ-AS subscales correlated positively with the ASI-R and the SATAQ-3.

TL;DR: A mediating effect of institutional trust and affective commitment on the relation between organizational justice and organizational citizenship behaviors was suggested and Affective commitment was shown to have a positive relation to organizational Citizenship behaviors.
Abstract: This study investigated the mediating role of institutional trust and affective commitment on the relationship between organizational justice and organizational citizenship behaviors. The study participants were 315 faculty members at 67 public/private universities of technology and vocational colleges in Taiwan. Structural equation modeling was used to analyze the relationships between the variables and assess the goodness of fit of the overall model. Organizational justice was positively related to institutional trust and there was an indirect effect of organizational justice on affective commitment through institutional trust. In addition, the relation between institutional trust and affective commitment was positive and affective commitment was shown to have a positive relation to organizational citizenship behaviors. Institutional trust was found to indirectly affect organizational citizenship behaviors through affective commitment. Most importantly, this study suggested a mediating effect of institutional trust and affective commitment on the relation between organizational justice and organizational citizenship behaviors. Implications, limitations, and future research were also discussed.

TL;DR: The Turkish version of the Tuckman Procrastination Scale scores correlated negatively with academic self-efficacy and self-esteem scores and provided evidence for the validity and the reliability of the scale scores.
Abstract: A stepwise validation procedure was carried out to translate and develop a Turkish version of the Tuckman Procrastination Scale. A total of 858 college students completed the Tuckman Procrastination Scale, the Academic Self-efficacy Scale, and the Rosenberg Self-esteem Scale. Two items in the original scale loaded on a different factor and were removed from the measure. The 14-item scale had a one-factor solution as supported by subsequent confirmatory factor analysis. The Turkish version of the Tuckman Procrastination Scale scores correlated negatively with academic self-efficacy and self-esteem scores. Overall results provided evidence for the validity and the reliability of the scale scores.

TL;DR: A random sample of 220 counseling center client records at a large Midwestern university, was used to assess reliability and validity of the Outcome Questionnaire–45.2 and internal consistency coefficients for the three subscales were acceptable.
Abstract: A random sample of 220 counseling center client records at a large Midwestern university, was used to assess reliability and validity of the Outcome Questionnaire-45.2 (OQ-45.2). The center uses the OQ-45.2 at intake. Internal consistency coefficients for the three subscales and the total score were acceptable, with high coefficients for the total score and Symptom Distress subscale and moderate coefficients for the Interpersonal Relations and Social Role subscales. Correlations among clients' presenting concerns and OQ-45.2 scores were computed and lend strong support for the validity of the OQ-45.2 total score and the Symptom Distress subscale. Weaker support was found for the Interpersonal Relations and Social Role subscales.

TL;DR: Significant negative correlations between mothers' depression and quality of life scores on all domains of the World Health Organization's Quality of Life-BREF (WHOQOL–TR) are indicated.
Abstract: This study aimed to compare the quality of life and depression levels in Turkish mothers of children with Down syndrome, cerebral palsy, and Autism Spectrum Disorder (ASD). An additional purpose is to identify whether the depression and quality of life levels of the mothers differ significantly based on demographic variables. Two hundred fifty-two mothers participated in the study. The World Health Organization's Quality of Life-BREF (WHOQOL-BREF-TR) assessment instrument was used to determine the mothers' quality of life and the Beck Depression Inventory (BDI) to characterize their depression. Mothers of children with cerebral palsy had significantly lower quality of life scores on the environment and national environment domains of the WHOQOL-BREF-TR than those of children with Down syndrome. No significant difference was observed in the depression of mothers. With increasing education and income, quality of life of the mothers increased whereas depression decreased. Moreover, depression increased and quality of life decreased in older mothers. Furthermore, the findings indicated significant negative correlations between mothers' depression and quality of life scores on all domains of the WHOQOL-BREF-TR.

TL;DR: Evidence of discriminant, convergent, incremental, concurrent, concurrent criterion-related, and construct validity for the Academic Equity Preference Questionnaire is provided.
Abstract: Members of Generation Y, or Millennials, have been accused of being lazy, whiny, pampered, and entitled, particularly in the college classroom. Using an equity theory framework, eight items from a measure of work entitlement were adapted to measure academic entitlement in a university setting in three independent samples. In Study 1 (n = 229), confirmatory factor analyses indicated good model fit to a unidimensional structure for the data. In Study 2 (n = 200), the questionnaire predicted unique variance in university satisfaction beyond two more general measures of dispositional entitlement. In Study 3 (n = 161), the measure predicted unique variance in perceptions of grade fairness beyond that which was predicted by another measure of academic entitlement. This analysis provides evidence of discriminant, convergent, incremental, concurrent criterion-related, and construct validity for the Academic Equity Preference Questionnaire.

TL;DR: Recollections of physical discipline as absent, age-delimited (ages 2–11), or present into adolescence were associated with youths' evaluations of their mothers' and fathers' parenting styles and their own adjustment.
Abstract: Recollections of physical discipline as absent, age-delimited (ages 2-11), or present into adolescence were associated with youths' evaluations of their mothers' and fathers' parenting styles and their own adjustment. Data were from the Portraits of American Life Study-Youth (PALS-Y) a diverse, national sample of 13- to 18-year-olds (N = 158). The modal experience of youth with authoritative parents was age-delimited spanking; the modal experience of youth with permissive parents was no spanking; the modal experience of youth with authoritarian or disengaged parents was physical discipline into adolescence. The age-delimited group reported the best adjustment (less maladjustment than the adolescent group; greater competence than both other groups). The positive association between fathers' age-delimited spanking and youths' academic rank persisted even after accounting for parenting styles. The eschewing of spanking should not be listed as a distinguishing characteristic of authoritative parenting, which was more often associated with age-delimited spanking than with zero-usage.

TL;DR: This study examined a new social construct called “entitativity” (i.e., the extent to which out-group members are perceived as bonded together in a cohesive or organized unit), as well as frequency of informal social contact and valence of a recent encounter in relation to certain xenophobic attitudes.
Abstract: An internet-related survey distributed to Norwegian students explored predictors of fear-related xenophobia toward immigrants. Specifically, this study examined a new social construct called "entitativity" (i.e., the extent to which out-group members are perceived as bonded together in a cohesive or organized unit), as well as frequency of informal social contact and valence of a recent encounter in relation to certain xenophobic attitudes. Correlational and multiple regression analyses indicated that perceived out-group entitativity was a moderate predictor of fear-related xenophobia. Voluntary informal contact was a weak predictor of fear-related xenophobia, whereas negative evaluation of an encounter in the recent past was a strong predictor. Further analysis indicated that the effect of entitativity on xenophobia was strongest when informal social contact was low. Moreover, analysis indicated that the effect of valenced contact was partly mediated through perception of entitativity. Language: en

TL;DR: Down-regulation seemed to be a more adaptive regulatory strategy than up-regulation in Chinese adolescents' emotional lives and its effect, using an Experience Sampling Method.
Abstract: The present study examined Chinese adolescents' emotion regulatory tendency and its effect, using an Experience Sampling Method. Participants comprised 72 Chinese adolescents (M age = 15.2 yr., SD = 1.7; 36 girls). Momentary emotional experience and regulation was assessed up to 5 or 6 times each day for two weeks. Results showed that participants tended to use up-regulation when they experienced positive emotion and habitually regulated their negative emotion by down-regulation. Also, adolescents who utilized down-regulation in a certain sampling moment reported higher positive emotion at the subsequent sampling moment. Moreover, adolescents who utilized down-regulation more frequently reported higher positive emotion at the subsequent sampling moment. Overall, down-regulation seemed to be a more adaptive regulatory strategy than up-regulation in Chinese adolescents' emotional lives.

TL;DR: The Italian version of the Teacher Stress Questionnaire showed satisfactory psychometric properties and constitutes a useful and reliable measure to analyse stress in Italian schools.
Abstract: This study analyses the psychometric properties of the Italian version of the Teacher Stress Questionnaire elaborated in England by Travers and Cooper in 1996. This Italian survey was completed by 863 teachers randomly drawn from a cross-section of Italian school levels. The construct validity of the questionnaire was verified by factor analysis and by measuring the internal consistency of the single scales. All dimensions measured by the Teacher Stress Questionnaire were compared for sample subgroups of all teacher levels. Several meaningful and reliable factors emerged from the factor analysis of the scales. The internal consistency of each scale (Cronbach's alpha) revealed satisfactory values. Teachers' age and school level were determining factors for all dimensions of stress explored. The Italian version of the Teacher Stress Questionnaire showed satisfactory psychometric properties and constitutes a useful and reliable measure to analyse stress in Italian schools.

TL;DR: Findings are consistent with the literature and provide further support for the idea that spirituality and health protective personality characteristics are related to and may promote better health resilience.
Abstract: Summary.—A growing body of research suggests there are important relationships among spirituality, certain personality traits, and health (organismic) resilience. In the present study, 83 college students from two southeastern universities completed a demographic questionnaire, the NEO Five Factor Inventory, and the Resilience Questionnaire. The Organismic resilience and Relationship with something greater subscales of the Resilience Questionnaire were used for analyses. Health resilience was associated with four of the Big Five personality variables and the spirituality score. Health resilience was positively correlated with ratings of extraversion, agreeableness, conscientiousness, and spirituality and negatively correlated with neuroticism. Forty-three percent of the variance of the health resilience score was accounted for by two of the predictor variables: spirituality and neuroticism. These findings are consistent with the literature and provide further support for the idea that spirituality and hea...

TL;DR: Supervisor and family support were found to be related negatively to two different aspects of work-family conflict, i.e., work interference with family and family interference with work, respectively, which was associated with employees' emotional exhaustion.
Abstract: With an increase of female workforce and dual-earner families, work-family conflict has received particular attention. Using a sample of 159 employees in South Korea, this study examined whether work-family conflict mediated the relationship between social support and emotional exhaustion. Supervisor and family support were found to be related negatively to two different aspects of work-family conflict, i.e., work interference with family and family interference with work, respectively. Also, each dimension of work-family conflict was associated with employees emotional exhaustion. The relationship between supervisor support and emotional exhaustion was mediated by work interference with family; whereas, the relationship between family support and emotional exhaustion was mediated by family interference with work. Implications and future research directions are discussed.

TL;DR: Path analysis results generally supported the suitability of the proposed model in which anxiety and depression mediated the effects of the materialism dimensions, “importance” and “success,” on addictive buying, and that depression also mediates the influence of the “ importance" and "happiness" dimensions.
Abstract: There is empirical evidence regarding the interrelationships between materialism, negative emotions, and addictive buying. The aim of this study was to clarify the direction of the relationships among these variables. Specifically, the main objective was to explore the possible mediating roles of anxiety and depression in the link between materialism and addictive buying. Path analysis results, using a sample of 685 women, generally supported the suitability of the proposed model in which anxiety and depression mediated the effects of the materialism dimensions, "importance" and "success," on addictive buying, and that depression also mediates the influence of the "importance" and "happiness" dimensions. Moreover, a direct effect of the importance dimension on addictive buying was found.

TL;DR: Students' academic achievement level was measured at four different points in time, until they finished the last course for their bachelor degrees, and a multivariate path analysis showed consistent relations between the motivational variables.
Abstract: Summary.—The present study investigated the joint effects of achievement motives, self-efficacy, and achievement goals as predictors of subsequent academic achievement among educational science students. A longitudinal research design allowed for measurement of motivational variables at several stages of education during bachelor courses (subsequent to the introductory courses), firstly by measuring achievement motives, secondly by self-efficacy and achievement goals. Subsequently, students' academic achievement level was measured at four different points in time, until they finished the last course for their bachelor degrees. A multivariate path analysis showed consistent relations between the motivational variables. The motive to avoid failure positively predicted the adoption of avoidance goals (both mastery and performance) and negatively predicted self-efficacy. Academic achievement was mainly predicted by the motive for success and performance-avoidance goals. The path analysis also showed strong re...

TL;DR: It is argued that the concept of “social network site” is not more specific than “Facebook,” so the assessment of addiction to social network sites in general would be more appropriate and defensible than the current Facebook addiction scale.
Abstract: Our recent paper about a new Facebook addiction scale has stimulated an interesting and very welcome debate among researchers concerning the assessment of excessive use of social networking sites. The critique put forward by Griffiths (2012) is mainly built on the conception of "Facebook" as too narrow of a concept, and that assessment of addiction to social network sites in general would be more appropriate. We argue that the concept of "social network site" is not more specific than "Facebook," so "Facebook addiction" rather than "social network addiction" is defensible. We acknowledge that more research in this area is needed and point specifically to new and important directions for future research that can shed light on the mechanism of addiction to social network sites.

TL;DR: The present study used The Young Adult Sleep Environment Inventory and sleep logs to investigate the sleep environment of college students living in residential halls and indicated that noise and light are significant sleep disturbances in these environments.
Abstract: College students regularly report increased sleep disturbances as well as concomitant reductions in performance (e.g., academic grades) upon entering college. Sleep hygiene refers to healthy sleep practices that are commonly used as first interventions in sleep disturbances. One widely used practice of this sort involves arranging the sleep environment to minimize disturbances from excessive noise and light at bedtime. Communal sleep situations such as those in college residence halls do not easily support this intervention. Following several focus groups, a questionnaire was designed to gather self-reported information on sleep disturbances in a college population. The present study used The Young Adult Sleep Environment Inventory (YASEI) and sleep logs to investigate the sleep environment of college students living in residential halls. A summary of responses indicated that noise and light are significant sleep disturbances in these environments. Recommendations are presented related to these findings.

TL;DR: The longitudinal predictions for depression and the test-retest reliability of the Brooding and Reflection of the Japanese RRS were partially consistent with those of other language versions (significant in almost all studies); however, longitudinal predictions of Reflection were not consistent with Those of otherlanguage versions (negative in previous studies).
Abstract: The Ruminative Responses Scale (RRS) is a measure of depressive rumination which has two subscales: Brooding and Reflection. This article examines the longitudinal predictions for depression and the test-retest reliability of the Brooding and Reflection of the Japanese RRS. Japanese university students (N = 378) completed the RRS, the Center for Epidemiologic Studies Depression Scale (CES-D), and the Inventory to Diagnose Depression, Lifetime Version (IDDL) which was modified to assess symptoms experienced in the 8-wk. follow-up period. The standardized betas of the initial Brooding and Reflection subscales for the IDDL scores were significant and positive after controlling for baseline CES-D scores, but those for the CES-D scores at Time 2 were not significant. Longitudinal predictions of Brooding were partially consistent with those of other language versions (significant in almost all studies); however, longitudinal predictions of Reflection were not consistent with those of other language versions (negative in previous studies). The test-retest correlations of both subscales were similar to those obtained in Western countries.

TL;DR: It was evident that sample sizes for most psychological studies are adequate for large effect sizes defined at .8, and it was perhaps doubtful if these ideal levels of alpha and power have generally been achieved for medium effect sizes in actual research, since 170 participants would be required.
Abstract: Tables of alpha values as a function of sample size, effect size, and desired power were presented. The tables indicated expected alphas for small, medium, and large effect sizes given a variety of sample sizes. It was evident that sample sizes for most psychological studies are adequate for large effect sizes defined at .8. The typical alpha level of .05 and desired power of 90% can be achieved with 70 participants in two groups. It was perhaps doubtful if these ideal levels of alpha and power have generally been achieved for medium effect sizes in actual research, since 170 participants would be required. Small effect sizes have rarely been tested with an adequate number of participants or power. Implications were discussed.

TL;DR: It was found that nurses dealing with critical cases and working in higher stress departments obtained higher mean scores on the Death Depression Scale, Death Obsession Scale, and Reasons for Death Fear Scale than their counterparts working in lower stress departments such as internal medicine.
Abstract: Summary.—A convenience sample of 195 volunteer nurses working in different medical departments was recruited (77 Kuwaiti, 118 non-Kuwaiti from 10 countries; 55 men, 140 women; ages 25 to 51 years). Participants responded in English to the Arabic Scale of Death Anxiety, the Death Depression Scale, the Death Obsession Scale, and the Reasons for Death Fear Scale. Pearson correlations between the four scales were statistically significant and positive. The only significant sex difference was on the Death Depression Scale with men reporting more stress. It was also found that nurses dealing with critical cases and working in higher stress departments (Intensive Care Unit and Heart Department) obtained higher mean scores on the Death Depression Scale, Death Obsession Scale, and Reasons for Death Fear Scale than their counterparts working in lower stress departments such as internal medicine. It was concluded that working in higher stress nursing departments affected death distress. Nurses with high scores on de...
