Cross-Sectional Evaluation of the Psychometric Properties of the Headache-Specific Locus of Control Scale in People With Migraine.
Trial report in Headache, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveThis study aims to investigate the psychometric properties (component structure, reliability, and construct validity) of the Headache-Specific Locus of Control scale in several clinical migraine populations.
backgroundHeadache-specific locus of control beliefs may impact a person's behavioral decisions that affect the likelihood of migraine attack onset, emotional responses to migraine attacks, coping strategies used, and treatment adherence. The 33-item Headache-Specific Locus of Control scale is the most widely used measure of locus of control specific to headache yet psychometric evaluations remain limited.
methodsSix hundred and ninety-five adults with a diagnosis of migraine from 5 different research studies completed cross-sectional self-report measures including the Headache-Specific Locus of Control scale and measures of quality of life and disability (Migraine-Specific Quality of Life Questionnaire and Migraine Disability Assessment).
resultsFive Headache-Specific Locus of Control components emerged from Horn's Parallel Analysis, Minimum Average Partial test, and Principal Component Analysis (eigenvalues: Presence of Internal = 5.7, Lack of Internal = 4.0, Luck = 2.9, Doctor = 2.0, and Treatment = 1.5). The 33 Headache-Specific Locus of Control items demonstrated adequate internal consistency for total (α = 0.79) and subscale scores (α's = 0.69 to 0.88). This study found preliminary evidence of convergent validity. For example, Lack of Internal (r = -0.12, P = 0.004), Doctor (r = -0.20, P < .001), and Treatment (r = -0.12, P = .004) beliefs were associated with higher overall migraine-specific quality of life impairments.
conclusionsThe Headache-Specific Locus of Control scale is a reliable and valid measure of headache-specific locus of control. Findings suggest that headache-specific locus of control is more multidimensional than previous conceptualizations and contribute to our understanding of control beliefs as a potential mechanism for migraine treatment.
