About This Measure
Categorical scoring:
Yes
Scoring categories:
Questions were scored using 4-point Likert scale: 1=not relevant; 2=somewhat relevant; 3=quite relevant; 4=very relevant. The score of each item ranges from 1 to 4. The total score of the scale is 36. A higher score represents a higher level of HL.
About the Validation of this Measure
Country where validated:
Iran
Content validity:
The development and validation of the tool included an expert panel, the translation of the measures from English to Persian were translated according to the International Quality of Life Assessment Project Protocol (LQOLA). In the expert panel reviews, all tasks received a CVI above 0.80 and CVR above 0.78, representing good content validity. Content validity index (CVI) and content validity ratio (CVR) were measured to evaluate the content validity of the HF-specific HL Scale. To obtain CVI for relevancy, we used simplicity and clarity of each item, ordinal scale with four possible responses. The responses include a rating from 1=not relevant, not simple and not clear to 4=very relevant, very simple and very clear. The number of those judging the item as relevant or clear (rating 3 or 4) was divided by the number of content experts. The acceptance of items based on CVI score was above 0.79 and CVR was higher than 0.8..
Reliability (Cronbach Alpha):
0.71
Reliability notes:
Test-retest reliability was assessed by computing the intra-class correlation coefficient (ICC) of each domain. The time interval for this assessment was two weeks. An ICC>0.80 indicated good test-retest reliability and stability. The Cronbach’s alpha of the total scale was 0.71, and test-rest reliability coefficient was 0.88 -0.90 for the subscales.
