„Rocken statt Ritzen“

Background

Non-suicidal self-injury (NSSI) starts in adolescence and decreases during young adulthood. Despite a high prevalence among adolescents only a few therapeutic interventions directly addressing adolescents exist.

Aim

By connecting music therapy with elements from behavioral therapy an attempt was made to create a therapeutic program which is attractive to adolescents.

Material and methods

A pilot trial of the program “Stop cutting - rock!” was conducted with 12 adolescent females with a mean age of 15.15 years (standard deviation SD ±1.34). The study aimed to compare the frequency of NSSI throughout the treatment phase as well as a pre-post comparison of depression scores.

Results

The results showed a trend towards a decreasing frequency of NSSI. Depression scores decreased significantly between the assessment before therapy and at a 3-month follow-up after the end of the therapy.

Conclusion

The positive feedback concerning music therapeutic elements points to the attractiveness of the approach. By integrating multimodal therapeutic strategies it seems possible to create an individually tailored intervention for adolescents with NSSI.     

Intramodal and crossmodal pairing and anchoring in comparisons of successive stimuli

Two experiments were conducted to study effects of modality, temporal position, and their interaction on comparisons of successive stimuli. In Experiment 1, intramodal (tone–tone and line–line) and crossmodal (tone–line and line–tone) stimulus pairs, with two interstimulus intervals (ISIs), 400 and 2,000 ms, were presented. Participants indicated which stimulus was the “stronger.” Time-order errors (TOEs) were assessed using the D% measure and were found in all types of pairs. Variation in TOEs across conditions was well accounted for by changes in parameters (stimulus weights, reference levels) in an extended version of Hellström’s sensation weighting (SW) model. With an ISI of 2,000 ms, the first stimulus had a lower weight (less impact on the response) than did the second stimulus. More negative TOEs were found with the longer ISI in all pair types except tone–line. In Experiment 2, participants indicated which of two lines was the longer or which of two tones was the louder. An intra- or crossmodal anchor, or no anchor, was interpolated between the stimuli. Anchoring tended to reduce the weight of the first stimulus, suggesting interference with memory, and to yield negative TOEs. Intramodal anchors yielded reduced weights of both stimuli, most dramatically for tones, suggesting an additional effect of stimulus interference. Response times decreased with crossmodal anchors. For line–line pairs, strong negative TOEs were found. In both experiments, the variation in TOE across conditions was well accounted for by the SW model.
