The validity and reliability of a "'standardized client" procedure for assessing the impact of counsellor-trainees ' behaviour upon client-perceived rapport was investigated within 22 counselling interviews. A typical client was trained to present the same genuine concern consistently across all interuiews, and to make minute-by-minute in-session ratings of experienced rapport. Data were collected on internal consistency, test-retest reliability, face validity, content, construct and concurrent validity via usual procedures and blind evaluations from professionals in the field. All common psychometric requirements were satisfied. Limitations of this procedure are discussed, and implications for use of "standardized client '' ratings to gather data on the rapport-enhancing effects of specific counsellor behaviours are also raised.

The effects of usage of eight verbal response modes by trainee counsellors during an initial interview were determined by reference to client-perceived rapport. Data on rapport were gathered via a standardized client's minute-by-minute ratings of his experience of rapport on a five-point scale during the interview. A total of ten counselling interviews were conducted, and data were examinedfor overall effects (i.e. during the interview as a whole) and minute-by-minute effects. Restatements, Minimal Encouragers and Verbosity were significantly dafferent in occurrence in high versus low rated interviews. Minute-by-minute data revealed that these overall differences were not consistent at all stages of the interviews. Implications for counsellor training are discussed.
