Assessment & Research

Initial encounters between people with a mild mental handicap and psychiatrists: an investigation of a method of evaluating interview skills.

Duckworth et al. (1993) · Journal of intellectual disability research : JIDR 1993
★ The Verdict

A 1993 rating scale reliably flags the best and worst psychiatrist interviews with adults who have mild intellectual disability.

✓ Read this if BCBAs who sit in on psychiatric evaluations or train clinicians in ID services.
✗ Skip if RBTs who only run direct instruction and never observe medical interviews.

01Research in Context

01

What this study did

The team built a simple rating scale for psychiatrists. Four trained judges watched first meetings between psychiatrists and adults with mild intellectual disability.

They scored how well each doctor asked questions, listened, and showed respect. Then they checked how much the four judges agreed.

02

What they found

The judges agreed moderately on most skills. They agreed most when picking the best and worst doctors.

The scale could tell strong interviews from weak ones, but middle performers were harder to rank.

03

How this fits with other research

Prasher et al. (1995) used the same idea two years later for people with profound ID. They added ratings for body language and facial cues.

Kleinert et al. (2007) moved from rating skills to making a full diagnostic interview. Their MASS tool gives psychiatrists exact questions to spot mood and anxiety disorders.

Windsor et al. (2025) later warned that most communication scales for ID still lack full validity. Their review includes the 1993 scale and urges more testing.

Chiviacowsky et al. (2013) showed most psychiatrists still feel under-trained for ID work, so clear rating tools stay important.

Why it matters

You now have a quick window into any doctor’s bedside manner. Use the scale items as a checklist when you observe psychiatrists or train new staff. If scores cluster at the top or bottom, you know whom to praise or coach. Share the mild-ID version with hospital partners and the profound-ID update for long-stay units.

03Original abstract

This study reports the results of an initial study into the ability of psychiatrists to interview people with a mild mental handicap who are accompanied by a caregiver. Initial interviews by 12 psychiatrists of different ages (30-57 years) and differing levels of experience with this client group were recorded on video tape. Three of the recordings were used to train four judges who were familiar with examining clinical interactions, though not between doctors and patients. The judges used a specially designed rating scale. The remaining nine interviews were evaluated independently by the four judges. There was a correlation of 0.65 (Kendall's coefficient of concordance, W) for the judges' evaluations using the rating scale for the nine interviewers. However, there was greater agreement between judges as to who were the best and worst interviewers (W = 0.86). Some of the aspects of the interviews which contributed to the variability in the judgments are discussed.
