The self-medication hypothesis of addictive disorders derives primarily from clinical observations of patients with substance use disorders. Individuals discover that the specific actions or effects of each class of drugs relieve or change a range of painful affect states. Self-medication factors occur in a context of self-regulation vulnerabilities--primarily difficulties in regulating affects, self-esteem, relationships, and self-care. Persons with substance use disorders suffer in the extreme with their feelings, either being overwhelmed with painful affects or seeming not to feel their emotions at all. Substances of abuse help such individuals to relieve painful affects or to experience or control emotions when they are absent or confusing. Diagnostic studies provide evidence that variously supports and fails to support a self-medication hypothesis of addictive disorders. The cause-consequence controversy involving psychopathology and substance use/abuse is reviewed and critiqued. In contrast, clinical observations and empirical studies that focus on painful affects and subjective states of distress more consistently suggest that such states of suffering are important psychological determinants in using, becoming dependent upon, and relapsing to addictive substances. Subjective states of distress and suffering involved in motives to self-medicate with substances of abuse are considered with respect to nicotine dependence and to schizophrenia and posttraumatic stress disorder comorbid with a substance use disorder.

Antecedents and consequences of problematic smartphone use: A systematic literature review of an emerging research area

Effects of maltreatment on coping and emotion regulation in childhood and adolescence: A meta-analytic review.

Background The percentage of smartphone users-especially among minors-is growing, and so is the body of literature hinting at increasing rates of problematic smartphone use in children and adolescents. However, comprehensive reviews regarding this issue are still scarce. Objective The main aim of this review was to provide an overview of studies focusing on specific risk factors predicting problematic smartphone use in children and adolescents. Methods A literature search was conducted in Google Scholar and PubMed. Results The search yielded 38 articles that met the criteria for inclusion in this review. Research regarding influencing factors such as gender, age, and social, family, and personality factors, as well as duration of use and use patterns, could be found. Results seem to cautiously suggest that using a smartphone for gaming and social networking might be risk factors, whereas having good friendships might constitute a protective factor. Also, female adolescents seem to be prone to a higher smartphone addiction risk than male adolescents. For family, school, and personality factors, results are still scarce, and more research is needed. Nevertheless, strict parenting, low self-control, and low self-esteem seem to increase risks for problematic use, whereas academic motivation and school success might decrease this risk. Conclusion A concise theoretical conceptualization of problematic smartphone use and corresponding standardized measures are needed to increase comparability of future studies and to thereby add to a clearer understanding of this contested concept.

Risk factors for problematic smartphone use in children and adolescents: a review of existing literature.

Due to the high accessibility and mobility of smartphones, widespread and pervasive smartphone use has become the social norm, exposing users to various health and other risk factors. There is, however, a debate on whether addiction to smartphone use is a valid behavioral addiction that is distinct from similar conditions, such as Internet and gaming addiction. The goal of this review is to gather and integrate up-to-date research on measures of smartphone addiction (SA) and problematic smartphone use (PSU) to better understand (a) if they are distinct from other addictions that merely use the smartphone as a medium, and (b) how the disorder(s) may fall on a continuum of addictive behaviors that at some point could be considered an addiction. A systematic literature search adapted from the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method was conducted to find all relevant articles on SA and PSU published between 2017 and 2019. A total of 108 articles were included in the current review. Most studies neither distinguished SA from other technological addictions nor clarified whether SA was an addiction to the actual smartphone device or to the features that the device offers. Most studies also did not directly base their research on a theory to explain the etiologic origins or causal pathways of SA and its associations. Suggestions are made regarding how to address SA as an emerging behavioral addiction.

Child neglect, psychological abuse and smartphone addiction among Chinese adolescents: The roles of emotional intelligence and coping style

Mindfulness and late adolescents' subjective well-being: The serial mediating roles of rejection sensitivity and self-esteem

OBJECTIVES
The protective role of self-compassion in emerging adult depression has garnered empirical support. It makes more sense to understand the psychological processes underlying this relationship. Based on the stress appraisal patterns, the present study examined the mediating roles of emotion regulation (ER) and resilience in the link between self-compassion and depression among college students with left-behind experience (LBE).


METHODS
A total of 391 LBE college students (Mage  = 18.43 years; SD = 0.79 years) in Chongqing reported their demographic information and self-compassion (the Self-Compassion Scale) level at baseline (T1) and reported their levels of ER (the Emotion Regulation Scale), resilience (the Connor-Davidson Resilience Scale), and depression (the Depression-Anxiety-Stress Scale) 3 months later (T2).


RESULTS
The results revealed that (a) both ER (cognitive reappraisal and expressive suppression) and resilience separately mediated the association between self-compassion and depression; (b) cognitive reappraisal and resilience sequentially mediated this association.


CONCLUSIONS
These findings reveal the underlying mechanisms of the associations between self-compassion and depression among LBE college students and have implications for interventions aimed at mitigating their depression.

Self-compassion and depression in Chinese undergraduates with left-behind experience: Mediation by emotion regulation and resilience.

Mental health problems among college students are increasingly prominent. The negative effects of emotional distress on college students' mental health have been supported empirically. It is important to understand the psychological processes underlying this relationship. Using a longitudinal design, the present study aimed to reveal the explanatory mechanism of the association between dimensions of dispositional mindfulness and mental health problems among Chinese college students by testing the mediating effects of experiential avoidance and intolerance of uncertainty. A total of 907 Chinese college students (57% male; Mage = 20.33 years) were invited to complete self-report questionnaires at two time points. Mindful awareness, acceptance and mental health problems (depression, anxiety and stress) were assessed at baseline (T0). Experiential avoidance, intolerance of uncertainty and mental health problems were assessed at the 6 month follow-up (T1). Following structural equation modeling (SEM) analyses, the results show that high levels of mindful awareness and acceptance may diminish mental health problems by decreasing the levels of experiential avoidance among college students. However, only mindful acceptance diminished mental health problems through decreased intolerance of uncertainty. In addition, our study found that mindful awareness and acceptance may have different functions when working alone. Specifically, these two constructs may have different relationships with mental health. Identifying these mechanisms by which dispositional mindfulness is associated with college students' mental health over time has potential value for the prevention of potential mental health issues and timely interventions.

Longitudinal Relationship Between Mindful Awareness, Acceptance and Mental Health Problems: A Mediation Model.

The harm of childhood parental neglect to emerging adults' maladjustment has garnered empirical support. For college students who have left-behind experience (LBE), this relationship is rarely discussed and the psychological process underlying this relationship is not well understood. Using a longitudinal study and guided by the Risky Families model, this study aimed to explore the mediating roles of anxious attachment and perceived social support in the link between parental neglect and maladjustment of LBE college students. We used two-wave longitudinal data, with a time lag of 3 months, collected among Chinese college students with LBE in Chongqing (N = 391). The results revealed that parental neglect in wave one was positively associated with maladjustment (depression, anxiety, and stress) in wave two. Anxious attachment and perceived social support in wave two separately mediated the relationship between parental neglect in wave one and maladjustment in wave two. Anxious attachment and perceived social support in wave two only sequentially mediated the pathway from parental neglect to later depression. These findings emphasize the importance of anxious attachment and social support in resilience and have significant implications for LBE college students' social work practice in China.
