Brief Summary

Background. The reduction of prevalence rates of Internet Use Disorder (IUD) and its effective treatment are at high priority in both public health and educational policies. School-based preventive interventions facilitate a low-threshold approach for individuals with IUD, who are typically characterized by high therapy avoidance. Moreover, indicated approaches which target adolescents at high-risk show larger effects than universal prevention approaches. Simultaneously, they reduce unnecessary burden for the majority of high-school students that is not at-risk. The PROTECT intervention for indicated prevention of IUD in school settings was developed based on these preventive strategies. Methods. Three-hundred and forty adolescents, aged 12-18 years, from 40 secondary schools in Germany, screened for high-risk of IUD onset, will be randomly assigned to a) PROTECT intervention group or b) assessment only control group. The tested intervention consists of a cognitive-behavioral 4-session brief-protocol. Follow-up assessments are at 1, 4 and 12 months after admission. Primary outcome is the 12-months incidence rate of IUD. Secondary outcomes are the reduction of IUD and comorbid symptoms and the promotion of problem solving, cognitive restructuring and emotion regulation skills. Discussion. The indicated preventive intervention PROTECT follows the APA-guidelines for psychological prevention. It is theory- and evidence-based (guideline 1) and addresses both risk-reduction and strength-promotion (guideline 3), it considers current research and epidemiology (guideline 4) and ethical standards (guideline 5) such as professional secrecy and is designed as a systemic intervention (guideline 8) at the school-level. It is expected that the intervention decreases risk of IUD onset (incidence rate).

Outcome Measures

Primary Outcomes (3)

  • Internet Use Disorder 12-months incidence rate (Clinical Interview for DSM-5 Diagnosis)

    We use a clinical interview (blinded rater) based on the criteria of Internet Gaming Disorder according to the DSM-5 at the 12-month follow-up. We adapted the criteria to assess IUD (including gaming and non-gaming subtypes).

    12 months

  • Internet Use Disorder 12-months incidence rate (Self-Report)

    We use the German "Computerspielabhängigkeitsskala" (CSAS; Rehbein, Baier, Kleimann \& Mößle, 2015), a self-report questionnaire which assesses DSM-5 criteria for Internet Gaming Disorder proposed in DSM-5 section 3 (American Psychiatric Association, 2013): (1) preoccupation, (2) withdrawal, (3) tolerance, (4) unsuccessful attempts to control, (5) loss of interest in other activities, (6) continued excessive use despite problems, (7) deception (8) maladaptive coping, (9) loss of relationship, job, or educational or career opportunities. We adapted the criteria to assess IUD (including gaming and non-gaming subtypes).

    12 months

  • Changes in Internet Use Disorder prevalence

    To measure the IUD prevalence rate over time (at baseline, 1 month, 4-months, 12-months), we use the adapted version of the CSAS questionnaire.

    baseline, 1 month, 4-months, 12-months

Secondary Outcomes (8)

  • Emotion Regulation

    baseline, 1 month, 4-months, 12-months

  • Depressive Symptoms

    baseline, 1 month, 4-months, 12-months

  • Comorbid emotional, oppositional, antisocial and attention deficit/ hyperactivity disorders

    baseline, 1 month, 4-months, 12-months

  • Anxiety Disorders: Social Anxiety

    baseline, 1 month, 4-months, 12-months

  • Anxiety Disorders: Performance and School Anxiety

    baseline, 1 month, 4-months, 12-months

Study Arms (2)

PROTECT intervention group

EXPERIMENTAL

The PROTECT intervention group receives the preventive intervention PROTECT (4 modules in 4 subsequent weeks à 90 min). Participants are assessed at T1 (baseline), T2 (post treatment, 1-month follow-up), T3 (4-months follow-up), and T4 (12-months follow-up).

Behavioral: PROTECT intervention group

Assessment-only control group

NO INTERVENTION

The assessment-only control group is an observational condition without intervention. Participants are assessed at T1 (baseline), T2 (1-month follow-up), T3 (4-months follow-up), and T4 (12-months follow-up).

Interventions

The indicated preventive intervention PROTECT consists of a cognitive-behavioral 4-session brief-protocol (90 minutes). It targets empirically identified risk factors of Internet Use Disorder (IUD), i.e. (1) boredom and motivational problems, (2) procrastination and performance anxiety, (3) social behavior and (4) emotion regulation. It addresses both risk-reduction and strength-promotion by cognitive behavioral (CB) interventions such as (1) psychoeducation, (2) cognitive restructuring (identification and modification of dysfunctional cognition), (3) behavior modification (improving problem solving skills, training of functional behavior and reinforcement) as well as (4) improving emotion regulation (training of sensory, imaginative and mindfulness based techniques).
