BACKGROUND
Mediation analysis investigates whether a variable (i.e., mediator) changes in regard to an independent variable, in turn, affecting a dependent variable. Moderation analysis, on the other hand, investigates whether the statistical interaction between independent variables predict a dependent variable. Although this difference between these two types of analysis is explicit in current literature, there is still confusion with regard to the mediating and moderating effects of different variables on depression. The purpose of this study was to assess the mediating and moderating effects of anxiety, stress, positive affect, and negative affect on depression.
METHODS
Two hundred and two university students (males = 93, females = 113) completed questionnaires assessing anxiety, stress, self-esteem, positive and negative affect, and depression. Mediation and moderation analyses were conducted using techniques based on standard multiple regression and hierarchical regression analyses.
MAIN FINDINGS
The results indicated that (i) anxiety partially mediated the effects of both stress and self-esteem upon depression, (ii) that stress partially mediated the effects of anxiety and positive affect upon depression, (iii) that stress completely mediated the effects of self-esteem on depression, and (iv) that there was a significant interaction between stress and negative affect, and between positive affect and negative affect upon depression.
CONCLUSION
The study highlights different research questions that can be investigated depending on whether researchers decide to use the same variables as mediators and/or moderators.

BACKGROUND AND OBJECTIVES
We examined whether technology-mediated communication has functional or emotional equivalence to face-to-face (FtF) contact in familial relationships, by scrutinizing the effects of phone, text/e-mail, and video contact on isolation and loneliness.
RESEARCH DESIGN AND METHODS
We tested whether FtF contact with a relative would mediate the pathway between proximity to family and (i) isolation and (ii) loneliness. We then tested hypotheses that telephone, text/e-mails, and video contact would moderate this mediated pathway. We compared models for younger (<75) and older (≥75) cohorts, expecting to observe moderation effects for text/e-mail and video contact in the younger cohort only. Data were drawn from Wave 2 of CFAS Wales (United Kingdom) study (N = 2,099).
RESULTS
Proximity to a relative had a significant indirect effect on isolation and loneliness through the mediating variable FtF contact. Phone and text/e-mail contact moderated the effect of FtF contact on isolation for all samples. None of the technologies moderated the impact of FtF contact on loneliness for the full sample. Telephone contact had a moderating influence on loneliness for the younger cohort only. Video calls had no significant moderation effect.
DISCUSSION AND IMPLICATIONS
Telephone and text/e-mail contact have functional equivalence to FtF contact in familial relationships. None of the forms of technological communication have emotional equivalence to the "gold standard" of embodied presence. The study demonstrates the importance of theorizing about the pathways to isolation and loneliness to better understand the likelihood of implementing successful interventions using technology-mediated communication within families.

INTRODUCTION
Loneliness is prevalent among young people. But, there is little work exploring the association between loneliness with well-being among this age group. Framed by social-ecological theory, we examined demographic, interpersonal, and community factors associated with personal wellbeing and, critically, identified malleable moderators of the relationship between loneliness and well-being that could be targeted in intervention efforts.
METHODS
We used cross-sectional, secondary data from 965 young people (aged 16-24) from the Community Life Survey in England. Loneliness was measured using a single-item direct measure; personal wellbeing was measured through a composite measure containing items assessing happiness, life satisfaction, and a sense that life is worthwhile (α = 0.88). Regression techniques were used to assess associations between individual, interpersonal, and community factors and well-being, and to identify moderators of the relationship between loneliness and well-being.
RESULTS
Loneliness was negatively associated with well-being. Chatting with neighbors and having people to provide help moderated the relationship between loneliness and well-being. Full-time students and those with good physical health had higher well-being while being a carer was predictive of lower well-being. All community variables were strongly associated with increased well-being. Of all interpersonal variables investigated, only having people to count on was associated with increased well-being.
CONCLUSIONS
Our results demonstrate that supportive relationships and close community ties are important for reducing the negative impact of loneliness on youth well-being. Interventions to improve well-being could benefit from targeting these aspects of young people's social and community lives, while acknowledging individual vulnerabilities, such as poor physical health.

Review
The theory of planned behavior (TPB) states that behavioral intention is the best predictor of actual behavior change. However, intention explains only a portion of the variance in behavior. Of specific interest is the question of which moderating or mediating variables can be leveraged to aid health promotion interventions utilizing the tenets of behavioral economics (delay discounting and commitment contracts) in the intention-behavior pathway. Impulsivity has been postulated to fill this role and may be applied to multiple behaviors. We aim to determine if impulsivity moderates the association between intention and actual behavior in the TPB, to discover what other variables may moderate or mediate this association, and to apply the findings to future studies in the field of behavioral economics. To this end, a systematic review was conducted using the PubMed, PsychINFO, and Embase online databases. Eligible studies in peer-reviewed journals published prior to November 2021 were selected. Thirty-three studies were included in the final review, examining physical activity, diet, preventive health, mental health, addiction, and medication adherence behaviors. Three main concepts emerged: (1) impulsivity moderates the association between intention and behavior change; (2) self-efficacy moderates the association between intention and behavior change; and (3) planning and self-efficacy contribute to moderated mediation. This review demonstrates a gap in the literature regarding the application of the TPB to the intention-behavior pathway for health behaviors. Future studies in behavioral economics may leverage the variables of impulsivity, self-efficacy, and planning to predict follow-through in this area and to develop targeted change initiatives.

BACKGROUND
Childhood maltreatment has been identified as a risk factor for depressive symptoms. Social anxiety is closely associated with depression. Physical activity has been regarded as an underlying protective factor. Little is known about the complex relations among these factors in Chinese middle school students. This study aimed to explore whether social anxiety mediated the association between childhood maltreatment and depressive symptoms and investigate whether physical activity moderated the indirect or direct effect of the mediation model.
METHODS
A total of 1,570 middle school students were recruited and measured for childhood maltreatment (measured by Childhood Trauma Questionnaire-Short Form Chinese version), social anxiety (as the mediator, measured by the Chinese simplified version of Social Anxiety Scale for Adolescents), depressive symptoms (measured by the Chinese version of Depression Anxiety Stress Scales-21), physical activity (as the moderator), and covariates such as age, sex, and nationality. The proposed relationships were tested using mediation and moderated mediation models.
RESULTS
Emotional abuse was directly associated with depression, and the association between emotional abuse and depression was partially mediated by social anxiety. The associations between emotional abuse with depression and with social anxiety were moderated by physical activity.
CONCLUSION
This study revealed the mediating role of social anxiety and the moderating role of physical activity between emotional abuse and depression, which emphasizes the potential benefits of sufficient physical activity to reduce social anxiety and depressive symptoms, and more intervention studies should be conducted to explore the direct influence of sufficient physical activity in the future.

There is vast evidence that accounts for the association between entrepreneurial orientation (EO) and the probability of starting a business (PSB). However, there are not many studies that test how psychological factors moderate this relationship. A variable that has been little studied in this relationship is Grit. Grit is considered a personality trait defined as perseverance and passion for long-term goals. Grit considers two sub-dimensions, one linked to the consistency of interests (Grit-Passion) and the other linked to perseverance in the effort (Grit-Perseverance). The objective of this article is to analyze the moderating role that both sub-dimensions of grit plays in the relationship between EO and PSB, considering its interaction with sociodemographic variables such as age, gender, and culture. This cross-sectional study has a sample of 1,761 participants, active workers (49.8% men; mean age 41.15 years, SD = 12.72 years; 22.9% Colombian and 77.1% Spanish). The EO scale and a Grit Scale were applied. In addition, participants were asked, based on their perception, how likely they were to start their own business within the next 5 years. A simple moderation analysis was considered to test the moderating role of grit in the relationship between EO and PSB. Subsequently, a double moderation analysis was carried out in order to identify which sociodemographic variables moderate the moderating effect of grit on the relationship in question. The results show that only the Grit-Passion component of grit moderates the relationship between EO and PSB. Regarding the sociodemographic variables, neither age, culture, nor gender showed a moderating effect on the moderation exercised by Grit-Passion in the relationship between OE and PSB. The results are discussed in terms of psychological capital, particularly with an emphasis on explaining why only the Grit-Passion shows a moderating effect on the relationship between EO and PSB, in detriment of Grit-Perseverance. In addition, the power of grit in the field of entrepreneurship is discussed, considering that its moderating effect is transversal to variations in age, gender and culture, as well as its relevance when considering interventions and pedagogical models in the field of entrepreneurship.

Review
: This brief review covers the current state of the literature on moderators of adolescent substance use disorder (SUD) treatment. These moderators provide information on "for whom" a specific treatment may work best.: We used Google Scholar, PubMed, PsycInfo, and manual search of relevant reference lists to identify eligible peer-reviewed publications from January 2005 to December 2019.: We summarize 21 published studies (including meta-analyses, randomized clinical trials, and correlational work) testing moderators and/or predictors of adolescent SUD treatment outcomes. Conclusions are, thus, limited by the relatively small number of studies. Results suggest that, for adolescents with co-occurring externalizing pathology or those higher in SUD severity, more intensive treatment appears to be more effective. Other findings were often inconsistent (e.g., examining sex or race/ethnicity as a moderator) between studies, making it challenging to provide clear recommendations for personalizing SUD treatment choice.: Future research may need to shift focus from exploring often unchangeable moderators (e.g., race/ethnicity) to factors that are potentially modifiable with treatment. Additionally, testing models that include mediators of treatment effects-that is, factors that help to explain "how" treatment works-along with moderators (moderated-mediation) may provide the most benefit in understanding both "for whom" and "how" to tailor SUD treatment to optimally meet an adolescent's personal needs.

OBJECTIVES
The COVID-19 pandemic has been associated with a dramatic rise in symptoms of depression and anxiety. Dispositional mindfulness (DM) and self-compassion (SC) have consistently been associated with psychological disorder symptoms and appear to buffer the effects of stress on depression and anxiety.
METHODS
Across two studies ( = 888), we examined direct and indirect (moderation) relationships of DM, SC, COVID-19-related stress, and symptoms of depression and anxiety. We also examined the differential effects of several DM measures (FFMQ-15; FFMQ-39; MAAS) in the relationships of COVID-19 stress and psychological disorder symptoms. We recruited participants (Study 1 = 350; 42.2% cis women; Study 2 = 538; 44.3% cis women) online (MTurk) and examined associations of DM, SC, and COVID-19 stress, and emotional impact, and the moderating effect of DM and SC in the relationships of COVID-19-related fears, stress, emotional impacts, and psychological disorder symptoms.
RESULTS
DM and SC were moderately and negatively correlated with COVID-19 fears and stress (correlations ranging = - .14 to = - .42) across studies. Study 1 moderation analyses demonstrated SC, but not DM (FFMQ-15), significantly moderated relationships of COVID-19 fears and emotional impacts with symptoms. Study 2 analyses demonstrated the FFMQ-39, but not the MAAS, significantly moderated relationships of COVID-19 stress and psychological disorder symptoms.
CONCLUSIONS
These results support the potential protective roles of DM and SC in disrupting pathological trajectories related to naturally elevated pandemic stress. Results also demonstrate the differential associations of several DM measures with COVID-19 stress. Future research should replicate such findings with more diverse samples and using various measures of self-compassion and risk metrics.

Randomized Controlled Trial
BACKGROUND
Individuals in stressful work environments often experience mental health issues, such as depression. Reducing depression rates is difficult because of persistently stressful work environments and inadequate time or resources to access traditional mental health care services. Mobile health (mHealth) interventions provide an opportunity to deliver real-time interventions in the real world. In addition, the delivery times of interventions can be based on real-time data collected with a mobile device. To date, data and analyses informing the timing of delivery of mHealth interventions are generally lacking.
OBJECTIVE
This study aimed to investigate when to provide mHealth interventions to individuals in stressful work environments to improve their behavior and mental health. The mHealth interventions targeted 3 categories of behavior: mood, activity, and sleep. The interventions aimed to improve 3 different outcomes: weekly mood (assessed through a daily survey), weekly step count, and weekly sleep time. We explored when these interventions were most effective, based on previous mood, step, and sleep scores.
METHODS
We conducted a 6-month micro-randomized trial on 1565 medical interns. Medical internship, during the first year of physician residency training, is highly stressful, resulting in depression rates several folds higher than those of the general population. Every week, interns were randomly assigned to receive push notifications related to a particular category (mood, activity, sleep, or no notifications). Every day, we collected interns' daily mood valence, sleep, and step data. We assessed the causal effect moderation by the previous week's mood, steps, and sleep. Specifically, we examined changes in the effect of notifications containing mood, activity, and sleep messages based on the previous week's mood, step, and sleep scores. Moderation was assessed with a weighted and centered least-squares estimator.
RESULTS
We found that the previous week's mood negatively moderated the effect of notifications on the current week's mood with an estimated moderation of -0.052 (P=.001). That is, notifications had a better impact on mood when the studied interns had a low mood in the previous week. Similarly, we found that the previous week's step count negatively moderated the effect of activity notifications on the current week's step count, with an estimated moderation of -0.039 (P=.01) and that the previous week's sleep negatively moderated the effect of sleep notifications on the current week's sleep with an estimated moderation of -0.075 (P<.001). For all three of these moderators, we estimated that the treatment effect was positive (beneficial) when the moderator was low, and negative (harmful) when the moderator was high.
CONCLUSIONS
These findings suggest that an individual's current state meaningfully influences their receptivity to mHealth interventions for mental health. Timing interventions to match an individual's state may be critical to maximizing the efficacy of interventions.

INTRODUCTION
Childhood abuse is linked to poorer well-being, yet some survivors show no prolonged effect, suggesting multifinality. Men and women also differ in the experience and sequelae of abuse supporting gender-specific analyses. To assist in circumventing poor outcomes associated with child abuse, this study examined fear of self (FoS) and self-compassion (SC) as risk and protective factors between child abuse and well-being.
METHOD
Australian women (N = 1302, M = 47.28 [13.63]) completed an online assessment of childhood abuse, psychological distress, perceived quality of life, SC, FoS. Moderated-moderation examined the different abuses as predictors of psychological distress and quality of life (QoL) and FoS and SC as primary and secondary moderators, respectively.
RESULTS
Physical abuse did not predict psychological distress or QoL. FoS and SC were independent predictors of distress and QoL. Similarly, childhood sexual abuse was not found to predict distress or QoL. FoS and SC were independent predictors of distress and QoL. There was also an interaction between childhood sexual abuse and SC in predicting QoL. A moderated-moderation was found for the relationship between child sexual abuse and distress. Psychological abuse predicted distress and QoL, and FoS and SC both moderated this relationship. Moreover, a moderated-moderation was observed for the relationship between psychological abuse and QoL.
CONCLUSIONS
Greater FoS is associated with poorer outcomes for child abuse survivors; SC may mitigate this impact. Psychological abuse was the strongest predictor of well-being. Interventions that increase SC and raise awareness of psychological abuse and its impacts are needed.
