The Effect and Experience of the Parental Program AFFEKT

Externalizing behaviors is a common problem among children. There are several parent programs for parents of children with externalizing behaviors, but many of these programs are time consuming. Within Medtanken Group AB a new brief parent program called AFFEKT has been developed. The clinical experience of the program has been promising, yet there are no previous randomized controlled trials or qualitative studies of AFFEKT.

The overall aim of this project is to examine the efficacy of the brief parenting program AFFEKT for parents of children with externalizing behaviors, and the parents experience of participating in AFFEKT. The project includes a quantitative study, including a randomized controlled trial (RCT), and a qualitative study.

Main aim and research question of the RCT part of the project:

The main aim of the RCT is to evaluate the efficacy of the brief parenting program AFFEKT. Is AFFEKT and psychoeducation targeting the parents more effective in changing the child's externalizing behaviors and mental health than psychoeducation alone? Primary research questions of the RCT

• Will the outcome concerning the children's problematic behaviors improve statistically and significantly more in the experiment group (psychoeducation + AFFEKT) than in the control group (psychoeducation alone) post treatment?
• Will there be statistical and significant effects of AFFEKT + psychoeducation on the children's problematic behaviors over time (6 and 12months after baseline)?

Secondary research questions of the RCT

• Will outcomes concerning the children's mental health improve statistically and significantly more in the intervention group (psychoeducation + AFFEKT) than in the control group (psychoeducation alone) post treatment?
• Will the parental sense of competence, strategies, mental health, and quality of life have improved significantly more in the intervention group (psychoeducation + AFFEKT) than in the control group (psychoeducation alone)?
• Will there be statistical and significant effects on the children's mental health, and the parent's sense of competence, strategies, mental health and quality of life over time (6 and 12months after baseline)?
• Will changes in the parent's sense of competence, parental strategies, mental health and health-related quality of life mediate the changes in the child's externalizing behaviors and mental health over time?

Aim and specific research questions for the qualitative part of the study:

• The main aim of the qualitative study is to examine parents experience of the intervention AFFEKT, and how they perceive their child and relation to their child after the program.
• What aspects of AFFEKT did the parent's find helpful and what knowledge do the parents perceive that they have gained from their participation in AFFEKT? How do the parents perceive those previous situations they found difficult before the parental program AFFEKT, after participation? And what have changed in these situations?
• How has the parent's perception of the child changed, and in what way have the parent's relation to their child, changed after their participation in AFFEKT? Are there differences in the mothers and fathers' experiences of AFFEKT? The sample in both studies will be parents searching help for their children with externalizing behaviors, within the context of primary health care. The clinics that will be recruiting participants are all driven by Medtanken Group, but within different municipalities and counties in the Region of Västra Götaland, Sweden.

Sample size was determined after a power analysis, using G*Power. The power analysis used an effect size of 0.50, an alpha level of 0.05, and a power of 0.80. The number of patients needed was 64 in each group (experiment, control). With consideration to drop-outs N=200 will be recruited to the RCT. The qualitative study will include a random sample of 30 of these participants (15 women, 15 men).

Methods for data collection

All parents in contact with the clinics meeting the inclusion criteria will be asked to participate in the project. The parents willing to participate will be booked for a digital group information meeting through Microsoft Teams. These information meetings will be held after 10-14 families at one of the included clinics have shown interest in the project. At these meetings the parents will receive verbal and written information about the RCT and qualitative study and leave their written and informed consent. The participants will then answer the baseline questionnaires online, receive psychoeducation from a brochure and get a brief standardized information about AFFEKT.

After the information meeting (baseline) a psychologist within Medtanken Group (not part of the research group) will randomly assign the participants (single parents as one unit and couples as one unit) to either experiment or control group, using randomizerorg.se. The allocation ratio will be 1:1. Since the information meetings will be held consecutively at each clinic the randomization procedure will be consecutive as well.

The outcome measures are all answered by the parents. Data will be collected at baseline, pretreatment (+7 weeks) for the control group, post treatment (+6 weeks for the experiment group and +11 weeks for control group), +6 and +12 months. The questionnaires at baseline, +6 and +12 months will be online, and the questionnaires at the start and end of AFFEKT will be in paper and pen. The study participants will receive a gift certificate after they have finished their AFFEKT group and after they have completed the study.

The qualitative study will use semi-structured interview-guides. The participants who have agreed to be contacted for participation in an interview about their experiences of AFFEKT will be contacted 3 weeks after the last session and asked if they still would like to participate. Interviews will be conducted online, through Microsoft Teams or at the clinic where the participants received their treatment. The participants of the qualitative study will also receive a gift certificate.

Methods for data analyses

The RCT study will follow CONSORT standards. A participant flow-chart will be developed. For each group baseline demographics and characteristics will be presented. Data analyses will include both Intention to treat (ITT) and per protocol (PP) analyses, meaning the intended parents to treat and the once that completed the program and follow-up registrations will be analyzed separately. The level of statistical significance will be held at alpha 0.05. Bonferroni Corrections will be used to handle multiple analyses. The last-observation-carried-forward technique will be used for imputing missing values due to dropouts in the ITT analyses. Missing values on item level will be imputed with the mean value of that subscale for that respondent. Binary outcomes will be presented in both relative and absolute effect sizes. For each outcome estimated effect sizes and confidence intervals will be presented. Between group analyses will include baseline data, pre- and post-intervention data. Within group analyses will include baseline data, post-intervention data, 6month data and 12month data. Growth Curve Models will be performed to examine mean level stability and changes in parental outcomes using baseline data, post-intervention data, 6month data and 12month data. The twelve month follow up will not enable comparisons between groups, since all participants by then have received the intervention, however the sustainability of the results post intervention can be analyzed. Subgroup analyses will be based on parental gender, socio-economic status, and the age of the children. A drop-out analysis will also be conducted including both descriptive and analyzing statistics.

The material from the qualitative study and interviews will be transcribed and qualitative analyses such as thematic analysis and thematic reflexive analysis will be used to explore the research questions.
