Development and Validation of a Scale to Assess the Helpfulness of Using Measures in Psychotherapy: The Patient-Perceived Helpfulness of Measures Scale (ppHMS)

Description

The Patient-Perceived Helpfulness of Measures Scale (ppHMS) was developed to assess the helpfulness—as perceived by patients—of using measures, particularly those for ROM, in psychological treatment. Measure development consisted of four stages. In Stage 1, the construct of patient-perceived helpfulness of measures was explored using thematic analysis with 15 clients. Six helpful and three unhelpful themes were identified and informed item development. Stage 2 consisted of expert ratings, psychometric shortening in a sample of 76 clients, and CFA. In Stage 3, we established a best fit 5-item model using a stratified online sample of 514 U.K. psychotherapy patients. The final ppHMS had excellent internal consistency (McDonald’s omega = .90), convergent validity with psychotherapy satisfaction (r = .5; p < .001), divergence from social desirability (r = .1), and metric and scalar invariance. In Study 4, analyses were replicated and confirmed in a stratified U.S. sample (n = 602). The ppHMS is a freely-available reliable and valid scale that can be used to assess and compare patients’ perceptions of the helpfulness of different ROM measures. It’s five items, rated from 1 (Strongly disagree) to 5 (Strongly agree) are: ‘1) I got something out of using this form’, ‘2) The form was a useful addition to what we did in therapy’, ‘3) This form got me thinking about what matters to me in therapy’, ‘4) Using this form made the therapy better’, ‘5) I learnt something from using the form in therapy’.
