Validation of the Perceived Neighborhood Environment Questionnaire for diabetes mellitus type 2 patients

Abstract

The success of diabetes mellitus type 2 (DMT2) therapy does not solely depend on laboratory test results, but is also influenced by the patients' quality of life (QoL). Patients' QoL is affected by numerous factors, including distress and their home environment. This study aims to acquire a valid and reliable instrument concerning neighborhood conditions felt by DMT2 subjects. The research applied a cross-sectional design with adult DMT2 patients at the Local General Hospital Moewardi Solo. The Perceived Neighborhood Environment Questionnaire (PNEQ) was translated from English to Indonesian with the procedure of forwardbackward translation. Statistical analyses were conducted to determine reliability, discriminant, convergent and known-group validity. The three domains of PNEQ have low reliability (Cronbach's alpha <0.7), while three questions have not met convergent validity and only one question has not attained discriminant validity. The PNEQ can be used on the Indonesian people with further explanations on questions that have not achieved reliability and validity.

Adaptation and validation of the HIV Knowledge Questionnaire-18 for the general population of Indonesia

“…The instrument's adaptation phase indicates that adding a few words or examples to explain the context of each item is extremely beneficial to participants' understanding. This approach has also been applied in other adaptation and validation studies in Indonesia [ 33 , 34 ]. Furthermore, based on factor analysis, we preferred to use two factors based on visual inspection of the scree tree.…”
