Brief Summary

A controlled pre-post design study on Take it Personal! has demonstrated effectiveness in reducing the frequency and severity of youth use of alcohol, cannabis or other illicit drugs. Take it Personal! is an existing indicated prevention programme for substance use in youth with a mild intellectual disability or borderline intellectual functioning that addresses each participant's high-risk personality traits for substance abuse. The current Take it Personal! programme is further developed and optimized in collaboration with relevant stakeholders. In particular, the investigators aim to integrate personalized daily diary monitoring in the programme so that trainers can monitor client progresses closely and gain insights into change mechanisms, providing starting points for therapeutic efforts in programme sessions. The investigators conduct a series of case studies with a non-concurrent multiple baseline design to evaluate the effectiveness of Take it Personal!. The baseline lengths are randomly determined, and therefore the start of the intervention is staggered across participants.

Outcome Measures

Primary Outcomes (1)

  • Change in daily substance use frequency

    Daily diaries include at least one item about substance use. Depending on which substance the individual uses, it will inquire after units of the substance used per day. For example, "how many glasses of alcohol did you drink today?" or "how many joints did you smoke today?"

    Through study completion, on average 90 days

Secondary Outcomes (3)

  • Change in daily personal behavioral problem

    Through study completion, on average 90 days

  • Change in substance use frequency

    Baseline, 1-month, 6-month, and 12-months

  • Experienced changes

    1 month

Interventions

Take it Personal! is a six-week indicated prevention program for youth with a mild intellectual disability or borderline intellectual functioning. The program aims to teach youngsters skills to reduce their substance use (alcohol, cannabis, and other drugs). The prevention program differentiates four personality profiles associated with a higher risk for problematic substance use: sensation seeking, impulsivity, anxiety sensitivity and negative thinking. For each of the four personality profiles, different program outlines were developed that are similar in structure but have their own personality-specific materials, games and (psychomotor) exercises. There are weekly individual- and group sessions with three to four participants, led by a clinical psychologist and a psychomotor therapist. Motivational interviewing and cognitive behavioral therapeutic principles are applied, both of which have proven effectiveness in decreasing substance use the target group.

Eligibility Criteria

Age14 Years - 30 Years
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Between 14 and 30 years of age
  • A DSM-5 based diagnosis of mild intellectual disability OR borderline intellectual functioning A mild intellectual disability is characterized by an intelligence quotient (IQ) score between 50-70 and limitations in adaptive behavior that impede a range of everyday social and practical skills. The DSM-5 describes borderline intellectual functioning as a condition in which a person's limited intellectual functioning is the focus of, or has an impact on, their treatment. This diagnosis is typically given when IQ is roughly between 70 and 85. Persons with either diagnosis often lead problematic lives, facing, for example, social and coping difficulties, and are vulnerable to the development of psychopathologies such as substance use disorder.
  • Receives specialized in- or outpatient care
  • Uses alcohol or drugs at least once per two weeks, as confirmed by participant's clinician
  • Owns a mobile phone
  • \- Moderate or severe substance use disorder

Will share

Preregistration, metadata and analyses scripts/syntax will be stored in the Open Science Framework (OSF; www.osf.io) and will be made findable and accessible publicly. The raw data (i.e., pseudonymized quantitative data in .csv of daily diaries, standardized surveys and anonymized transcripts of the client change interviews), as well the metadata, will be made findable and openly accessible on the repository of Radboud University: Radboud Repository. A persistent identifier will be made through OSF, which is then also included in the Radboud Repository. Hence, we use only one DOI. Sensitive data cannot be made publicly accessible. Therefore, audio recordings of the interviews nor any contact information (names, e-mail addresses, addresses) are not accessible.
