Outcome measures
Primary outcome
The main study parameters are:
- Implicit action tendencies to hair pulling-related stimuli
- Severity and frequency of hair pulling
- Relapse
Secondary outcome
- Response inhibition
- Urge and resistance with respect to hair pulling
- Self-control cognitions
- Attentional biases towards hair pulling-related stimuli
- Implicit evaluations of hair pulling-related stimuli
Background summary
Rationale: The present study investigates implicit processes in trichotillomania (TTM). Previous research has shown that different implicit biases are found in unwanted habitual behaviour. In a study by Wiers, Eberl, Rinck, Becker, & Lindenmeyer on severe alcoholics (2011) an implicit training targeting action tendencies was added to standard treatment. Alcoholics that received training showed significantly less relapse one year after treatment. Adding this implicit training component to standard treatment may improve long-term treatment outcome in TTM also.
Objective: The primary objective of this study is to investigate whether adding the implicit training component to standard treatment improves long-term treatment effects in patients suffering from TTM. The second goal is to contribute to the knowledge about TTM and unwanted habits in general and investigate the underlying mechanisms of unwanted habits to improve future psychological treatment possibilities.
Study objective
The implicit training (AAT) added to standard behaviour therapy will reduce relapse rates after treatment when compared to the control group.
Study design
Before training, after training/before therapy, after therapy, 1, 3 and 12 month follow-up
Intervention
Behaviour therapy
Plus either implicit training aimed at decreasing an approach bias towards hair pulling, or a general implicit training
Inclusion criteria
The inclusion criteria are an age between 18 and 65 and a current primary diagnosis of TTM.
Exclusion criteria
Exclusion criteria are a current psychotic episode, substance abuse disorder, and an inability to speak and understand Dutch. Patients who refuse the computer training are also excluded from the study. They are offered standard behaviour therapy, however.
