VALIDATION OF THE HUMAN ACTIVITY PROFILE QUESTIONNAIRE BY TELEPHONE CALL IN CARDIOVASCULAR DISEASE PATIENTS (Preprint)

BACKGROUND To validate the application of the Human Activity Profile (HAP) questionnaire via telephone call in patients with cardiovascular disease (CVD). OBJECTIVE Objective of this study is to investigate the validity of applying the HAP questionnaire via telephone call to patients with cardiovascular disease participating in a cardiovascular rehabilitation program. METHODS Two scores were calculated based upon HAP scores: the maximum activity score (MAS), the number of the most difficult task the respondent is “still doing”; and the adjusted activity score (AAS), the number of items that the individual “stopped doing”, prior to the last one that he “still does”. Patients with CVD answered the HAP questionnaire on 2 random occasions, face-to-face and by telephone call. RESULTS Fifty-six patients with CVD (64.30% men) with a mean age of 75.14±10.28 years participated in this study. The MAS was similar in both applied modes (Face-to-face: 79.11±11.48; Telephone call: 82.71±7.48; p=0.101). Similarly, The AAS did not differ in both applied modes (Face-to-face: 69.11±14.18; Phone call: 71.21±13.43; p=052). There was high agreement between the two modes of administration (ICC - 0.999; 95%CI, 0.879-0.948; p<0.05). The mean bias and 95% limits of agreement evaluated by Bland-Altman plot for average applied face-to-face and the telephone call versus the mean difference in the MAS and AAS applied face-to-face and the telephone call were, respectively, -4.0 (95%CI 12.1 to -19.3) and -2.1 (95%CI 13.4 to -17.6). CONCLUSIONS The MAS and AAS from HAP can be applied over the telephone call in patients with CVD. CLINICALTRIAL CAAE 58283422.0.0000.5134 (number: 5.646.387)
