Development, Validity, and Reliability of the Primary Eye Care Questionnaire (PECQ) Among Optometrists in Malaysia.
Article in Cureus, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionVisual impairment and vision loss are preventable or treatable if there is access to eyecare services for early detection and if proper interventions are given. Optometrists play a vital role in the early detection of eye and visual-related issues. As healthcare professionals, optometrists are trained to provide comprehensive eye and vision care encompassing dispensing and refraction, detection of abnormalities in the vision and eye, and the rehabilitation of conditions of the visual system, as suggested by the World Council of Optometry.In the current practice of primary eye care, optometrists are not fully utilized and are mostly restricted to refractive correction. Therefore, the optometrists' practice level, scope, and challenges to practice primary eye care must be identified before strengthening optometrists' role in the community.
objectiveThe present study aimed to develop and validate a questionnaire to determine the contributing factors and challenges to the practice of primary eye care by optometrists in Malaysia.
methodsThe Primary Eye Care Questionnaire (PECQ) was developed through an extensive literature search to identify the domains and to construct the items. The items were then scrutinized further through focus group discussions with experts (n = 10) from various sectors of eye care. Content validation was conducted with ophthalmologists and optometrists as panels (n = 10), followed by face validation (n = 10) by optometrists from the public and private sectors. Construct validation was performed with exploratory factor analysis and reliability was evaluated by using Cronbach's alpha coefficient and the test-retest reliability.
resultsIn total, the PECQ questionnaire was constructed with 123 items under three main domains: contributing factors, challenges, and continuous education. The content validity index (CVI) for each item (I-CVI) score ranged from 0.9 to 1.0 for each item and the CVI for average scale (S-CVI/Ave) was above 0.8 for each domain, with internal consistency of 0.948 and Cronbach's alpha coefficient of 0.971.
conclusionThe PECQ is a valid and reliable tool for assessing the optometrists' scope of practice, challenges, and contributing factors to the practice of primary eye care.
