Efficacy of digital mental health interventions for PTSD symptoms: A systematic review of meta-analyses.

BACKGROUND: The present systematic review aimed to synthesize the results of meta-analyses which examine the effects of digital mental health interventions (DMHIs) on post-traumatic stress disorder (PTSD) symptoms, and investigate whether intervention characteristics (i.e., technique, timeframe, and therapeutic guidance) and methodological characteristics including outcome measures and sample inclusion criteria (age, gender, socioeconomic status, country, comorbidity) moderate the efficacy of digital interventions. METHODS: A systematic search of various sources (ECSCOhost PsycInfo, PubMed, Web of Science, Scopus, EBSCOhost ERIC, Google Scholar, ProQuest Dissertations & Theses) including five peer-reviewed journals was conducted to identify relevant meta-analyses up to December 2023, and 11 meta-analyses were included in the final review. RESULTS: Overall, our review elucidates that DMHIs are appropriate for alleviating PTSD symptoms in adults, with more consistent evidence supporting the efficacy of cognitive behavioral therapy (CBT)-based, compared to non-CBT-based, interventions when compared to control conditions. However, we found inconclusive evidence that the efficacy of DMHIs varied according to intervention timeframe, therapeutic guidance, or sample characteristics. LIMITATIONS: A relatively limited number of different populations was sampled across meta-analyses. Further, while our review focused on PTSD symptoms to indicate the efficacy of digital interventions, other indices of effectiveness were not examined. CONCLUSION: Our findings indicate the clinical utility of DMHIs for managing PTSD symptoms particularly when CBT-based intervention techniques are employed.

Social anxiety and emotion regulation flexibility: a daily diary approach.

Previous research suggests that social anxiety symptoms are maintained and intensified by inflexible emotion regulation (ER). Therefore, we examined whether trait-level social anxiety moderates ER flexibility operationalised at both between-person (covariation between variability in emotional intensity and variability in strategy use across occasions) and within-person (associations between emotional intensity and strategy use on a given day) levels. In a sample of healthy college-aged adults (N = 185, Mage = 21.89), we examined overall and emotion-specific intensities (shame, guilt, anxiety, anger, sadness) and regulatory strategies (i.e. experiential avoidance, expressive suppression, and rumination) in response to each day's most emotionally intense event over 6 days. During the study period, we found a positive association between variability in emotional intensity and variability of experiential avoidance in individuals with lower, rather than higher, levels of trait social anxiety after controlling for key covariates (i.e. gender, personality traits, and stress exposure). However, we did not find evidence for the moderating role of trait social anxiety in ER flexibility assessed at within-person levels. Our findings highlight the need to delineate dynamic ER flexibility across everyday events.

A Daily Diary Investigation of the Fear of Missing Out and Diminishing Daily Emotional Well-Being: The Moderating Role of Cognitive Reappraisal.

With modern societies becoming ever-increasingly interconnected due to technology and media, we have gained unprecedented access and exposure to other people's lives. This has resulted in a greater desire to constantly be socially connected with the activities of others, or the fear of missing out (FoMO). While much of the present available research has established the association between FoMO and diminished emotional well-being, little has been done to identify protective factors that can help one cope with the negative psychological consequences of FoMO. Utilizing data from a 7-day diary study of a large sample of young adults (N = 261), the current study aimed to examine the moderating role of cognitive reappraisal in attenuating diminished emotional well-being associated with FoMO. Multilevel modeling showed that cognitive reappraisal attenuated the day-to-day within-person associations between daily FoMO and indicators of daily emotional well-being such as negative affectivity, anxiety, and depressive symptoms.

Potential and Pitfalls of Mobile Mental Health Apps in Traditional Treatment: An Umbrella Review.

While the rapid growth of mobile mental health applications has offered an avenue of support unbridled by physical distance, time, and cost, the digitalization of traditional interventions has also triggered doubts surrounding their effectiveness and safety. Given the need for a more comprehensive and up-to-date understanding of mobile mental health apps in traditional treatment, this umbrella review provides a holistic summary of their key potential and pitfalls. A total of 36 reviews published between 2014 and 2022-including systematic reviews, meta-analyses, scoping reviews, and literature reviews-were identified from the Cochrane library, Medline (via PubMed Central), and Scopus databases. The majority of results supported the key potential of apps in helping to (1) provide timely support, (2) ease the costs of mental healthcare, (3) combat stigma in help-seeking, and (4) enhance therapeutic outcomes. Our results also identified common themes of apps' pitfalls (i.e., challenges faced by app users), including (1) user engagement issues, (2) safety issues in emergencies, (3) privacy and confidentiality breaches, and (4) the utilization of non-evidence-based approaches. We synthesize the potential and pitfalls of mental health apps provided by the reviews and outline critical avenues for future research.

Interactional Effects of Multidimensional Perfectionism and Cognitive Emotion Regulation Strategies on Eating Disorder Symptoms in Female College Students.

Given the inconclusive findings regarding the relation between perfectionism and eating disorder symptoms, it is important that we determine whether this relation is modulated by emotion dysregulation, which is a prominent risk factor for eating disorders. We sought to identify specific cognitive emotion regulatory strategies-rumination, self-blame, and catastrophizing-that interact with multidimensional perfectionism to shape eating disorder symptoms (i.e., shape, weight, eating concerns, and dietary restraint). Using latent moderated structural equation modeling, we analyzed data from 167 healthy young female adults. We found that only rumination significantly moderated the relation between socially prescribed perfectionism and eating disorder symptoms. However, this was not observed for self-oriented perfectionism or other regulatory strategies. These findings held true when a host of covariates were controlled for. Our findings underscore the crucial role of rumination, a modifiable emotion regulatory strategy, in augmenting the relation between socially prescribed perfectionism and eating disorder symptoms in young women.

Loneliness, Sense of Control, and Risk of Dementia in Healthy Older Adults: A Moderated Mediation Analysis.

Objectives: Despite the rising prevalence of dementia, little research has been conducted to identify modifiable psychological factors that alleviate the risk of dementia in older adults and the underlying mechanisms. Given that loneliness is, in part, concomitant with a weakened sense of control, we examined whether sense of control would mediate the relation between loneliness and dementia risk. Further, considering that working -memory capacity is a critical cognitive resource that serves as a buffer against age-related cognitive decline, we examined a second-order moderated mediational model whereby working-memory capacity moderates the relation between control beliefs and dementia risk in older adults. METHODS: We administered a series of measures to older community-dwelling adults (ages 60-93; N = 69), including the participant-rated AD8 to assess the risk of dementia. Using the PROCESS macro, we examined the moderated mediation model for the relation between loneliness, sense of control, and dementia risk. RESULTS: We found that sense of control significantly mediated the relation between loneliness and risk of dementia. Moreover, the indirect effect of loneliness on dementia risk via lowered sense of control was significant only in individuals with poorer working-memory capacity. Notably, these findings held true when important covariates were controlled for. CONCLUSIONS: Our findings underscore the critical role of control beliefs and working memory in protecting against dementia risk. CLINICAL IMPLICATIONS: Our findings have implications for intervention programs that target alleviating dementia risk and promoting healthy aging in older adults by improving socioemotional health and cognitive functioning.

Effects of Social Media and Smartphone Use on Body Esteem in Female Adolescents: Testing a Cognitive and Affective Model.

We examined the predictive relations of social media and smartphone use to body esteem in female adolescents and the mechanism that underlies these relations. As a result of frequent social media and smartphone use, adolescents are continually exposed to appearance-related media content. This likely reinforces a thin ideal and fosters appearance-based comparison and increases fear of external evaluation. Hence, we investigated a cognitive-affective framework in which the associations of social media and smartphone use with body esteem are serially mediated by cognitive internalization of an ideal body image, appearance comparisons, and social appearance anxiety. By testing female adolescents (N = 100) aged 13 to 18, we found that excessive social media use leads to unhealthy body esteem via intensified cognitive internalization, which aggravates appearance comparisons and anxiety regarding negative appearance evaluation. Further, we found that screen time for specific smartphone activities also harmed body esteem, independent of social media use. However, overall smartphone screen time did not affect body esteem when social media use was taken into consideration. Our findings underscore the multifactor mechanism that elucidates the negative impacts of social media and smartphone activities on body esteem in female adolescents, who are developmentally susceptible to poor body esteem.
