Introduction: This longitudinal case-controlled study examined the effects of universal parent-focused interventions on parents' perceived competence in terms of parental efficacy and satisfaction. Method:The study sample consisted of parents from northern Sweden in the general population who participated in parent training programmes from 2010 to 2013, and a matched-comparison group. All parents had children aged 0-17. Sense of competence was measured by the Parenting Sense of Competence Scale at pre-and post-intervention and six months after the intervention. Results:The intervention group showed a statistically significant improvement in parental competence compared to the comparison group over time. The intervention itself had a significant effect on parental satisfaction, but the efficacy effect was not sustained when taking into account potential confounders. Conclusions:Earlier studies indicate that parent training programmes enhance perceived parental competence amongst referred parents. The present study shows that parent training programmes applied in the general population may also enhance perceived parental satisfaction, suggesting that parent training programmes can be an important preventive strategy to enhance parental feelings of satisfaction in the wider population. The results suggest that parents who participate in parent training programmes might have a need to increase parental competence, based on lower scores than the comparison group, both before and after the intervention.

The study aims to investigate the effects of Parent Training Programs on the mental health of parents with children aged between 1 and 17 in a universal preventive setting. The intervention group included 279 parents who were assigned to five professionally administered interventions, which included 5-10 two-hour sessions; they were then compared to 702 parents in the comparison group without intervention. The improvement in general mental health was statistically significant in the intervention group compared to the comparison group. The findings suggest that evidence-based parent training programs enhance well-being in parents without indicated problems. However further exploration of preventive training programs for parents are needed.

This is a confirmatory study that assessed the effects of parent training programs on parental stress in a general population. There is a need to repeat and confirm earlier findings to acquire solid knowledge for policy stakeholders. In a quasi-experimental design, self-reported data were gathered at three occasions from 83 parents of children between the ages from one to ten years. These parents had responded to advertisements of parent training programs, and were matched to a comparison group of 83 parents chosen from a governmental database. Parent training program based upon behavioral, cognitive-behavioral, Adlerian and family system-theories. Parental stress due to incompetence, role restriction, social isolation, spousal relationship problems, and health problems were measured by the Swedish Parenthood Stress Questionnaire that is based on the Parent Stress Index Scale. The data indicated a reduction of stress in the sub-scale of health problems among parents in the intervention group with an effect size of 0.33, however, no other subscale showed the intervention as a significant variable when controlling for confounding variables. This study adds on the accumulated knowledge of supporting interventions for parents. We conclude that parent training programs have a significant effect on the stress components of parental health when implemented in real-life settings.

Schools are an important arena to curb the decline in physical activity (PA) in youth. School-based interventions with accelerometer-measured PA are warranted. This study aimed to increase accelerometer-measured PA in adolescents following a 12-month school-based intervention. Two school-classes of 16–18-year-old Swedish students were allocated to intervention group and control group. Accelerometer-measured PA was gathered at baseline, 6- and 12-month follow-up. Mixed-effects linear regression was used to investigate between-group and within-group differences in mean minutes per day (min/day) of moderate to vigorous PA (MVPA), light PA (LPA) and sedentary time (ST). Fifty-seven students participated (intervention group = 31, control group = 26). At 12-month follow-up, the intervention group performed 5.9 (95% CI: −4.3, 16.2) min/day more in MVPA, 1.8 (95% CI: −17.9, 14.2) min/day less in LPA, and 4.1 (95% CI: −27.3, 19.2) min/day less in ST compared to the control group. Within the intervention group, there was no significant change in PA. Within the control group, LPA decreased (95% CI: −19.6, −0.2; p = 0.044) and ST increased (95% CI: 1.8, 30.8; p = 0.028). Although no between-group differences in PA were statistically significant, the within-group changes may suggest a preventive impact on the decline in PA during adolescence.
