Dave Walsh & Mick King, University of Derby, UK. Getting better all the time?
Aim of study: To examine how well investigators evaluate their own interview skills Post-PEACE: (some) areas of interviewing have improved (Clarke & Milne, 2001; Griffiths & Milne, 2006; Griffiths, 2008; Leahy-Harland, 2011; Soukara, Bull, Turner, Vrij, & Cherryman, 2009; Shawyer, 2009; Walsh & Bull, 2010; 2012; Walsh & Milne, 2008) iNTRODUCTION
Problems with…. • Training alone will not lead to sustained improved performance(Holton, Bates, Seyler, & Carvalho, 1997; Rouiller & Goldstein, 1993; Yammill & Mclean, 2001). • with supervision (Clarke & Milne, 2001; Stockdale, 1993; Walsh & Milne, 2007) • expectations after training (Shepherd & Griffiths, 2013) • understanding what is good interviewing (Cherryman, 2000; Walsh & Bull, 2011) Reasons for continuing indifference in performance
Self evaluation involves “a high level of self-awareness and the ability to monitor one’s own learning and performance” (Cassidy, 2006, p. 170). Highly demanding skill (Argyris & Schön; 1978) Persistence in undertaking the task enables effective self-evaluation (Hanrahan & Isaacs, 2001; Stefani, 1998) and perceptions of improved performance (Walsh & Milne, 2007) Importance of self –evaluation
Investigators from GLA – entire investigation personnel Undertook a training exercise involving a simulated interview Measured for skill levels using an assessment scale (46 dimensions) – evolved from Bull & Cherryman, 1995; Clarke & Milne, 2001; Griffiths, 2008; Walsh & Bull, 2010; Walsh & Milne, 2008) Dichotomous - and Likert scales; 1 – poor , 5 – highly skilled Overall interviewing skill Methodology
By participants themselves at end of training from video-taped recording • By researchers after training from video-taped recording • Between researchers to ensure inter-rater reliability Stages of measurement
Between experts Assessor 2 examined 50% of Assessor 1’s sample (N=9) All correlations significant (where p = ≤.01) at ≥ .82 except ‘Overall interview’ score; 0.64, p = <0.05. Inter-rater scores
Between expert and investigator (self –assessed) • Correlations significant • Appropriate structure 0.71, p= <0.01 • Topic development (0.49), Points to prove (0.54), Conversation management (0.59), Cognitive interview (0.49), Intermittent summaries (0.46)- all significant; p = <0.05 • All other correlations (inc. ‘overall assessment) scored no more than 0.22, all being n.s., except ‘Self confidence’; 0.45,n.s.

Investigators seemingly tend to self-enhance Exaggerated scores after training Some tend to be overly self-critical Few accurate self-assessments Self-evaluation as a basis for self-improvement? Implications for prActice
Investigators submitted 2000 word reflective self- assessments To be compared to their/our rating scales Interview skills to be measured again 12 months after training from field interviews Also questionnaire relating to self-evaluation task Is there improvement/deterioration/maintenance in performance levels Is there any association between performance (improved/deteriorated/maintained) levels and self-reports of undertaking self-evaluation task future developments
