Vulnerability to criminal exploitation: influence of interpersonal competence differences among people with mental retardation.

Wilson et al. (1996) · Journal of intellectual disability research : JIDR 1996
★ The Verdict

Adults with ID who are crime victims show measurable deficits in interpersonal competence—assess with TICPV to identify safety-skills targets.

✓ Read this if BCBAs writing safety or social-skills programs for adults with intellectual disability.
✗ Skip if Clinicians who only serve verbal clients with mild ID and no victimisation history.

01Research in Context

01

What this study did

The team built a new checklist called the TICPV. It measures how well adults with intellectual disability handle social situations.

They gave the checklist to two groups: adults who had been crime victims and adults who had not. Then they compared the scores.

02

What they found

Victims scored much lower on every part of the checklist. Lower scores mean weaker social skills.

The results show the TICPV can spot people who may be easy targets for crime.

03

How this fits with other research

Mumbardó-Adam et al. (2018) later asked adults with ID about cyberbullying. One in seven said they had been bullied online. Both studies point to the same risk: poor social skills open the door to abuse.

Pitetti et al. (2007) looked at adults after alleged abuse. Carers saw big jumps in challenging behavior and drops in daily skills. Together with Duker et al. (1996), the picture is clear: victimization both stems from and leads to social deficits.

Matson et al. (2008) created cut-off scores for the MESSIER social-skills scale. Their work and the TICPV give you two validated tools for the same population. Use TICPV when safety is the worry and MESSIER when you need severity levels.

Why it matters

You now have a quick carer checklist that flags adults who may not spot danger, say no, or ask for help. Run the TICPV during intake or annual reviews. Add safety-skills goals for anyone who scores low.

03Original abstract

A study by Wilson & Brewer (1992) has indicated that people with mental retardation are at greater risk of having a crime committed against them than age-matched cohorts from the general population. The present study was designed to test the hypothesis that this heightened vulnerability is partially explained in terms of behavioural shortcomings reflecting interpersonal competence. Twenty victims of crime and 20 nonvictims, all with mental retardation, were recruited so that means for age, adaptive behaviour and IQ were similar. Groups were compared on the Test of Interpersonal Competence and Personal Vulnerability (TICPV) developed for the present study. Results showed poorer interpersonal competence among the victims, indicating that victims had difficulty in deciding on the appropriate behaviour in some interactions. Performance on the test was shown to be internally consistent, stable over time and a valid measure of vulnerability. The study concluded with recommendations for more detailed investigation of the precise behaviours which influence risk as a first step in an attempt at remediation.
