Goal Setting and Self-Efficacy Among Delinquent, At-Risk and Not At-Risk Adolescents

Technology-Delivered Psychotherapeutic Interventions in Improving Depressive Symptoms Among People with HIV/AIDS: A Systematic Review and Meta-analysis of Randomised Controlled Trials

With the increasing popularity of advanced technology, technology-delivered psychotherapeutic interventions (TPIs) may play a promising role in improving depressive symptoms among PLWHA. However, its effectiveness remains unclear. We aimed to synthesise the evidence of the effectiveness of TPIs in improving depressive symptoms of PLWHA using a meta-analytic approach. Seven databases were systematically searched for randomised controlled trials (RCTs) from the inception until August 14, 2018. Random-effects meta-analysis was adopted to assess effect size. Cochran's Q test and I² were used to investigate the problem of heterogeneity. Sensitivity, subgroup analyses and meta-regression were performed. Of the 43,048 records identified, 14 RCTs were included. The meta-analysis revealed a small effect on reducing depressive symptom scores (d = 0.23, 95% CI - 0.39 to - 0.06) after TPIs. Random-effects meta-regression showed that publication year was a significant moderator (p = 0.013), whereby the latest trials had larger effect size in reducing the depressive symptoms than earlier trials. Our review suggested a possible future approach of utilising TPIs by means of mobile applications and internet-based interventions for PLWHA to reduce their depressive symptoms. This review highlighted the essential key features in designing future TPIs. The overall low-quality evidence suggested the need to conduct further high-quality.

Personalised eHealth interventions in adults with overweight and obesity: A systematic review and meta-analysis of randomised controlled trials

Given that many existing electronic health (eHealth) interventions with a general approach have limited effects, a personalised approach is necessary. We aimed to evaluate the effectiveness of personalised eHealth interventions in reducing body weight and identify the effective key features of such interventions. We searched seven databases for randomised controlled trials (RCTs) from inception until September 6, 2018. Of the 26,733 records identified, 15 RCTs were included. Meta-analysis revealed a significant reduction (-2.77 kg, 95% confidence interval - 3.54 to -2.00 kg) in the personalised eHealth intervention group compared with that in the control group (Z = -7.04, p < .001). The duration of the interventions ranged from 14 weeks and three trials had follow-up assessments at 6 and 12 months. Our subgroup analyses highlighted several crucial design elements of future personalised eHealth interventions by utilising a combination of tailored content and customised feedback with human feedback, usage of theoretical basis, short message service, device, reminder, self-monitoring, goal setting and synchronous communication for 12 to 14 weeks. Egger's regression asymmetry test suggested no evidence of publication bias (p = .458). Using meta-regression we found evidence that a statistically significant impact of age and year of publication on the effectiveness of intervention. The overall evidence grade of outcomes ranged from very low to low, hence future trials should use well-designed RCTs.

Internet-based self-monitoring interventions for overweight and obese adolescents: A systematic review and meta-analysis

BACKGROUND

Internet-based self-monitoring intervention offers accessibleand convenient weight management. This review aimed to systematically review the evidence on the effectiveness of internet-based self-monitoring intervention for overweight and obese adolescents.

METHOD

PubMed, CINAHL, Cochrane Library, EMBASE, ProQuest, PsycINFO and SCOPUS were systematically searched for randomised controlled trials (RCTs) from inception until December 13, 2017. The risk of bias and strength of evidence was assessed using the Cochrane Collaboration Risk of Bias Tool and the Grading of Recommendations, Assessment, Development and Evaluations criteria. Meta-analysis was performed on the RevMan software using a random effects model. The overall effect was assessed using effect size (Cohen'sd)and heterogeneity was evaluated using Cochrane Q and I2 values. PROSPERO database #CRD42016050089.

RESULTS

A total of 6841 records were identified. Six RCTs in 10 articles were selected amongst 505 adolescents across three countries who were overweight and obese. The meta-analysis revealed a small effect on the reduction of body mass index (BMI) and BMI z-scores (d = 0.30, 95% CI: -0.48 to -0.12). Subgroup analyses suggest the use of daily multicomponent self-monitoring, specified goal setting, face-to-face counselling and parental involvement. The overall quality of evidence was low due to the risk of bias and imprecision.

CONCLUSION

Internet-based self-monitoring intervention is a possible approach for overweight and obese adolescents to reduce their BMI. Further well-designed RCTs with follow-up data and large sample sizes are needed to ensure the robustness of the evidence.

Why Information Matters: Examining the Consequences of Suggesting That Pedophilia Is Immutable

In this study, the impact of suggesting that pedophilia is immutable on a man's specific self-efficacy for modifying his sexual interest in children was examined in 94 men with a sexual interest in children. The participants were selected from differing contexts and included non-forensic patients, forensic patients, and participants from the Internet. Randomly distributed to two conditions, the mutable condition group received the information that experts consider pedophilia to be modifiable, whereas the immutable condition group received the information that experts consider pedophilia to be stable. Afterward, the participants' levels of specific self-efficacy for modifying their sexual interest in children were assessed. Non-forensic participants in the mutable condition reported higher levels of specific self-efficacy than those in the immutable condition. No differences in specific self-efficacy were revealed for the forensic and Internet participants when comparing the mutable and immutable conditions. It would appear appropriate to avoid generalized and absolute statements about the (im)mutability of sexual interest in children, as scientific research on this topic remains insufficient. Furthermore, given the present results, such statements might have serious consequences for an individual's belief in being able to change his sexual interest in children.

The Role of Social-Emotional and Social Network Factors in the Relationship Between Academic Achievement and Risky Behaviors

BACKGROUND

We examined whether standardized test scores and grades are related to risky behaviors among low-income minority adolescents and whether social networks and social-emotional factors explained those relationships.

METHODS

We analyzed data from 929 high school students exposed by natural experiment to high- or low-performing academic environments in Los Angeles. We collected information on grade point average (GPA), substance use, sexual behaviors, participation in fights, and carrying a weapon from face-to-face interviews and obtained California math and English standardized test results. Logistic regression and mediation analyses were used to examine the relationship between achievement and risky behaviors.

RESULTS

Better GPA and California standardized test scores were strongly associated with lower rates of substance use, high-risk sexual behaviors, and fighting. The unadjusted relative odds of monthly binge drinking was 0.72 (95% confidence interval, 0.56-0.93) for 1 SD increase in standardized test scores and 0.46 (95% confidence interval, 0.29-0.74) for GPA of B- or higher compared with C+ or lower. Most associations disappeared after controlling for social-emotional and social network factors. Averaged across the risky behaviors, mediation analysis revealed social-emotional factors accounted for 33% of the relationship between test scores and risky behaviors and 43% of the relationship between GPA with risky behaviors. Social network characteristics accounted for 31% and 38% of the relationship between behaviors with test scores and GPA, respectively. Demographic factors, parenting, and school characteristics were less important explanatory factors.

CONCLUSIONS

Social-emotional factors and social network characteristics were the strongest explanatory factors of the achievement-risky behavior relationship and might be important to understanding the relationship between academic achievement and risky behaviors.
