Abstract

Insights

The Persian version of the 8-item Morisky Medication Adherence Scale (MMAS-8) is reliable for assessing medication adherence in diabetes mellitus patients. However, further research is needed to establish its validity.

Area of Science:

  • Endocrinology
  • Psychometrics
  • Public Health

Background:

  • Diabetes mellitus (DM) poses a significant global health challenge.
  • Medication adherence is vital for successful diabetes management.
  • The 8-item Morisky Medication Adherence Scale (MMAS-8) is a key tool for assessing adherence.

Purpose of the Study:

  • To evaluate the psychometric properties of the Persian version of the MMAS-8.
  • To determine the reliability and validity of the MMAS-8 in Iranian diabetic patients.

Main Methods:

  • The MMAS-8 was translated into Persian and administered to 150 diabetic patients.
  • Psychometric properties were assessed using Cronbach's alpha for reliability.
  • Data were collected from the Internal Medicine clinic of Firooz Abadi Hospital, Tehran, Iran (2018-2020).

Main Results:

  • The mean MMAS-8 score was 4.97 ± 1.92.
  • The Persian MMAS-8 demonstrated good internal consistency (Cronbach's α = 0.70).
  • No significant relationship was found between MMAS-8 categories and diabetes complications.

Conclusions:

  • The Persian MMAS-8 is a reliable instrument for measuring medication adherence in diabetic patients.
  • The study suggests the scale has acceptable reliability but requires further validation.
  • Additional research is recommended to enhance the validity of the Persian MMAS-8.

Reliability and Validity01:29

Reliability and Validity

Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Self-Report Tests of Personality

Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

Methods of Documentation II: POMR

The Problem-Oriented Medical Record (POMR) revolutionized medical record-keeping by introducing a systematic approach focusing on the patient's problems rather than merely listing symptoms. Dr. Lawrence Weed's introduction of this method in the 1960s marked a significant advancement in medical documentation. The POMR framework consists of four key components: the database, problem list, plan of care, and progress notes.

The Self-Evaluation Maintenance (SEM) model offers a psychological framework to understand how individuals’ self-esteem is influenced by the achievements of others, particularly those with whom they share close personal bonds. The SEM model operates when personal rather than social identity guides individuals. Central to this model is the notion that individuals have an inherent desire to preserve a favorable self-image, which is continuously shaped by interpersonal comparisons and...

Self-Discrepancy Theory

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.
