“…These refer to the agreement between two or more instruments that measure the same attribute, whose application occurred at different times, in a short time interval 32 and was applied to the same individuals. 1,3,27 It is the administration of alternative forms of the same measurement for the same or different groups.…”

“…The original questionnaire can be reformulated to measure the same attribute or construct, or rather, both the questions and the answers can be reformulated or their order changed so as to produce two items whose object of evaluation is similar but not identical. 32 Therefore, the greater the degree of correlation between the two forms, the more equivalent the measures would be.…”

“…33 However, there are criticisms regarding the use of this method, as in studies evaluating subjective variables, for example, quality of life in the general population, it is not common to have two instruments considered equivalent, 7 and the construction of equivalent / similar forms would make the process even more costly. 32 However, one situation in which equivalence may be applicable is when the measurement process involves subjective judgments and must be performed by more than one person. As with testretesting, parallel-form testing involves administration to the same people on two separate occasions.…”

Objective: to present and discuss conceptual bases and evaluation methods that support important properties of measurement instruments.Method: a theoretical study based on the international and national literature and the Consensus-based Standards for the selection of health Measurement Instruments e Evaluating the Measurement of Patient-Reported Outcomewhich contemplates concepts of evaluation of instruments for the evaluation of results reported by the patient. Initially, the concepts of reliability, responsiveness and interpretability are mentioned and discussed, as well as the main ways of evaluating the properties Results: it can be seen that there are still differences in some conceptual descriptions. However, the authors emphasize the importance of reliability in order to evaluate the measuring instrument. It is important to note the importance of knowing and understanding the Conceptual Model, the properties of measurements and the different evaluation methods that guarantee reliable and valid results, especially in the instrument validity studies.Conclusions: the discussion presented on reliability, responsiveness and interpretability which contributes to health professionals with theoretical knowledge, and a critical sense in the choice of instruments and in conducting analyzes on these measurement properties.DESCRIPTORS: Data accuracy. Psychometry. Validation studies. Surveys and questionnaires. Precision of dimensional measurement.

“…It can be measured by estimating correlation coefficients. Reliability can be measured in terms of stability, equivalence and internal consistency (Bolarinwa, 2015). The testretest method is used to assess stability, to ensure that same results are obtained when the same participant completes the questionnaire twice at different times.…”

Depression explanatory models of primary care patients and doctors: Relationship with self-stigma, communication effectiveness, and recovery

This thesis examines the role of patient and doctor perspectives in primary care depression management. The analytical term chosen to explore these perspectives is Kleinman's explanatory model (EM), defined as "notions about an episode of sickness and its treatment that are employed by all those engaged in the clinical process" (1980, p. 105). This research is exploratory and focuses mainly on patients, with input from a small number of general practitioners (GPs).I examine self-stigma in depression patients because there has been an attempt in recent years to reduce stigma by describing depression as a medical condition like diabetes. This may have decreased some public stigma, but the association between biomedical explanations for depression and patient self-stigma has not been studied in-depth. Self-stigma is the internalisation of negative stereotypes and prejudices about having mental illness and it can inhibit help-seeking and outcomes more than public stigma. Another factor that can influence depression outcomes is the therapeutic relationship between patient and their doctor. Studies report empathy and good communication as Quantitative analysis methods mainly consisted of non-parametric tests for differences between groups and strength of correlations. Interviews were analysed manually and with textual analysis software Leximancer.RQ1 results showed that most participants had a strong or moderate belief about whether biomedical and/or psychosocial factors caused their depression, and most EM beliefs did not change over time. RQ2 results indicated that biomedical belief was associated with lower helpseeking inhibition but also greater alienation. RQ3 results highlighted that endorsement of GPpatient cooperation was strongly positively correlated with communication effectiveness. Patient interviews yielded exemplars to illustrate these findings. RQ4 results from a paired study (n = 29) suggest that the GPs were aware of and concordant with their patient's EMs. Awareness appears to be more important in determining recovery than concordance. Incidentally, GP interviews showed that doctors mostly accorded importance to knowing their patient's EM but concordance was seen as less crucial.This thesis gives new understanding about depression EM beliefs that are associated with lower patient self-stigma and more effective GP-patient communication. Results from this research on awareness-concordance were not generalisable due to the small sample size, but future work with larger samples will undoubtedly yield more insights into the importance of EMs in primary care depression management.
