Objective 
This study was designed to investigate the revised and short version of the smartphone addiction scale and the proof of its validity in adolescents. In addition, it suggested cutting off the values by gender in order to determine smartphone addiction and elaborate the characteristics of smartphone usage in adolescents.


Method 
A set of questionnaires were provided to a total of 540 selected participants from April to May of 2013. The participants consisted of 343 boys and 197 girls, and their average age was 14.5 years old. The content validity was performed on a selection of shortened items, while an internal-consistency test was conducted for the verification of its reliability. The concurrent validity was confirmed using SAS, SAPS and KS-scale. Receiver operating characteristics analysis was conducted to suggest cut-off.


Results 
The 10 final questions were selected using content validity. The internal consistency and concurrent validity of SAS were verified with a Cronbach's alpha of 0.911. The SAS-SV was significantly correlated with the SAS, SAPS and KS-scale. The SAS-SV scores of gender (p<.001) and self-evaluation of smartphone addiction (p<.001) showed significant difference. The ROC analysis results showed an area under a curve (AUC) value of 0.963(0.888–1.000), a cut-off value of 31, sensitivity value of 0.867 and specificity value of 0.893 in boys while an AUC value of 0.947(0.887–1.000), a cut-off value of 33, sensitivity value of 0.875, and a specificity value of 0.886 in girls.


Conclusions 
The SAS-SV showed good reliability and validity for the assessment of smartphone addiction. The smartphone addiction scale short version, which was developed and validated in this study, could be used efficiently for the evaluation of smartphone addiction in community and research areas.

The smartphone addiction scale: development and validation of a short version for adolescents.

Background and aims The usage of smartphones has increased rapidly in recent years, and this has brought about addiction. The aim of the current study was to investigate the relationship between smartphone use severity and sleep quality, depression, and anxiety in university students. Methods In total, 319 university students (203 females and 116 males; mean age = 20.5 ± 2.45) were included in the study. Participants were divided into the following three groups: a smartphone non-user group (n = 71, 22.3%), a low smartphone use group (n = 121, 37.9%), and a high smartphone use group (n = 127, 39.8%). All participants were evaluated using the Pittsburgh Sleep Quality Index, Beck Depression Inventory, Beck Anxiety Inventory; moreover, participants other than those in the smartphone non-user group were also assessed with the Smartphone Addiction Scale. Results The findings revealed that the Smartphone Addiction Scale scores of females were significantly higher than those of males. Depression, anxiety, and day...

Modeling habitual and addictive smartphone behavior

Objective
The aim of this study was to develop a self-diagnostic scale that could distinguish smartphone addicts based on the Korean self-diagnostic program for Internet addiction (K-scale) and the smartphone's own features. In addition, the reliability and validity of the smartphone addiction scale (SAS) was demonstrated.

Sexual harassment is a serious problem, and with a growing population of college students in China, the phenomenon is becoming prevalent. Using the 2010 data from the Third Survey on Chinese Women’s Social Status, we examined relationships between understanding of sexual harassment and experience/response among Chinese college students. The results show that college students understand physical sexual harassment better (88%; unwanted sexual requests: 92%) than verbal and visual sexual harassment (54% and 70%, respectively). Understanding is higher among females than males, with a margin between eight to 21%. At a prevalence of 30%, the experience of verbal sexual harassment is the highest compared to other forms of harassment. Males were more likely to experience verbal and visual sexual harassment, while females were more likely to experience physical sexual harassment. In any event of sexual harassment, expressing dissatisfaction and stopping it is the response strategy that most resonates with respondents. It varied between 62% and 70% across forms of sexual harassment. Reporting to teachers or school authorities resonates least, varying between 0.30% and 2.28%. Understanding sexual harassment was strongly associated with a reduced likelihood of harassment. The equivalent odds ratios varied between 0.41 and 0.33 (p < .001), or 59–67% reduced likelihood across the forms of sexual harassment. Understanding sexual harassment was also strongly associated with an increased likelihood of not reacting passively or staying silent. Odds ratio varied between 1.99 and 3.86 (p < .001), about a minimum of twofold increased likelihood. Parents should strive to involve in their children’s sex and sexual rights education, particularly during adolescence, to help them inculcate values against sexual harassment. Also, colleges and universities can bolster their curriculum with elective courses on sex education and regularly organize symposiums on sexual harassment to create a better understanding and awareness among students.

Do Financial Inclusion and Income Inequality matter for Human Capital? Evidence from Sub-Saharan Economies

Self-criticism represents a central phenomenon among a variety of psychological distress and has been shown to relate to the motivational systems of competing and social ranking. The purpose of our study was to test the effect of online compassion-focused therapy (CFT)-based intervention (CFI) on Chinese international students in South Korea suffering from high self-criticism and related psychological distress. Thirty-two Chinese international students with a high level of self-criticism were randomized to either a four-session CFI group, a four-session rational emotive behavior therapy (REBT)—based online self-help approach group, or a wait-list (WL) control group. The results suggest that the CFI group demonstrated significant improvements in self-criticism, compassion, depression, anxiety, and shame, and these were greater than those in the REBT and WL groups. Our work provides evidence that CFI offers a possible approach for reducing self-criticism and related psychological distress and increasing compassion level for young Chinese populations.
