Validation of the Recent Life Changes Questionnaire (RLCQ) for stress measurement among adults residing in urban communities in Pakistan.

BACKGROUND: Recent Life Changes Questionnaire (RLCQ) developed by Richard Rahe has enabled quantification of stress by analyzing life events. The overall aim of the study was to create a reliable version of the Rahe's RLCQ for measuring stress in individuals living in developing countries and assess its validity. This paper discusses criterion validation of the adapted RLCQ in urban communities in Pakistan. METHODS: This is a criterion validation study. Four urban communities of Karachi, Pakistan were selected for the study in which households were randomly chosen. Two data collectors were assigned to administer the adapted RLCQ to eligible participants after obtaining written informed consent. Following this interaction, two psychologists interviewed the same participants with a diagnostic gold standard of Mini International Neuropsychiatric Interview (MINI) which is utilized in usual practice within Pakistan to confirm the presence of stress related mental disorders such as Depression, Anxiety, Dysthymia, Suicide, Phobia, OCD, Panic Disorder, PTSD, Drug abuse and dependence, Alcohol abuse and dependence, Eating Disorders and Antisocial Personality Disorder to validate the accuracy of the adapted RLCQ. We generated the ROC curves for the adapted RLCQ with suggested cut-offs, and analyzed the sensitivity and specificity of the adapted RLCQ. RESULTS: The area under the receiver operating characteristic curve (ROC) of common mental disorders such as depression and anxiety was 0.64, where sensitivity was 66%, specificity was 56% and the corresponding cut off from the adapted RLCQ was 750. Individuals scoring ≥750 were classified as high stress and vice versa. In contrast, the area under the ROC curve for serious mental disorder and adverse outcomes such as suicide, bipolar and dysthymia was 0.75, where sensitivity was 72% and specificity was 60% at the cut off of 800 on the adapted RLCQ. Individuals scoring ≥800 were classified as high stress and vice versa. The rate of agreement between the two psychologists was 94.32% (Kappa = 0.84). CONCLUSION: The adapted and validated RLCQ characterizes common mental disorders such as depression and anxiety with moderate accuracy and severe mental disorders such as suicide, bipolar and dysthymia with high accuracy.

Making prescriptions "talk" to stroke and heart attack survivors to improve adherence: Results of a randomized clinical trial (The Talking Rx Study).

BACKGROUND: We developed and tested the effectiveness of a tailored health information technology driven intervention: "Talking Prescriptions" (Talking Rx) to improve medication adherence in a resource challenged environment. METHODS: We conducted a parallel, randomized, controlled, assessor-blinded trial at the Aga Khan University (AKU), Karachi, Pakistan. Adults with diagnosis of cerebrovascular accident (CVA) or coronary artery disease (CAD) diagnosed least one month before enrollment, on anti-platelets and statins, with access to a mobile phone were enrolled. The intervention group received a) Daily Interactive Voice Response (IVR) call services regarding specific statin and antiplatelet b) Daily tailored medication reminders for statin and antiplatelet and c) Weekly lifestyle modification messages for a period of 3 months. We assessed Medication adherence to statin and antiplatelets by a validated version of the 8-item Morisky Medication Adherence scale 8 (MMAS-8) at 3 months by a blinded assessment officer. Analysis was conducted by intention-to-treat principle (ITT). RESULTS: Between April 2015 and December 2015, 197 participants (99 in intervention and 98 in the usual care group) enrolled in the Talking Rx Study. The dropout rate was 9.6%. Baseline group characteristics were similar. At baseline, the mean MMAS-8 was 6.68 (SD = 1.28) in the intervention group and 6.77 (SD = 1.36) in usual care group. At end of follow-up, the mean MMAS-8 increased to 7.41(0.78) in the intervention group compared with 7.38 (0.99) in usual care group with mean difference of 0.03 (S.D 0.13) (95% C.I [-0.23, 0.29]), which was not statistically significant. (P-Value = 0.40) CVA patients showed a relatively greater magnitude of adherence via the MMAS-8 at the end of follow up where the mean MMAS-8 increased to 7.29 (S.D 0.82) in the intervention group as compared to 7.07(S.D 1.24) in usual care group with mean difference of 0.22 (SD = 0.22) 95% C.I (-0.20, 0.65) with (P-value = 0.15). Around 84% of those on intervention arm used the service, calling at least 3 times and listening to their prescriptions for an average of 8 minutes. No user was excluded due to technologic reasons. CONCLUSION: The use of a phone based medication adherence program was feasible in LMIC settings with high volume clinics and low patient literacy. In this early study, with limited follow up, the program did not achieve any statistically significant differences in adherence behavior as self-reported by the MMAS-8 Scale.
