Validity and reliability of the motivation for physical activity (RM4-FM) questionnaire
2021
There is a lack of validated instruments measuring motivation for physical activity (RM4-FM) in the Finnish language. The study examined the translated RM4-FM instrument’s psychometric properties in a sample of healthy, older Finnish adults. RM4-FM was translated and linguistically validated adhering to published guidelines. 65–75-year olds (n=102), completed the RM4-FM, the physical activity acceptance questionnaire (PAAQ) and sociodemographic characteristics questionnaires electronically. The RM4-FM was readministered one month after the initial assessment. RM4-FM translated well into Finnish. Motivation dimension scores were skewed towards high internal and low external motivation. A flo…
Intra- and inter-rater reliability of thoracic spine mobility and posture assessments in subjects with thoracic spine pain
2020
Abstract Background The thoracic spine (TS) has been neglected in the study of the spine despite its essential role in the stability and posture of the entire spinal complex. Therefore, there is an inevitable need to investigate the reproducibility of different thoracic spinal posture measures used in subjects with TS pain. Methods Thirty-two subjects (16 females and 16 males, mean age 39 years) were evaluated by two physiotherapists on the same day to gauge inter-rater reliability and on two consecutive days to gauge intra-rater reliability. TS posture was assessed by observation, and thoracic spine mobility was measured by manual assessment of segmental flexion and extension mobility in a…
Reliability of upper-limb diaphyseal mineral and soft-tissue measurements using peripheral quantitative computed tomography (pQCT)
2018
Objectives: To quantify between-day reliability of upper-body diaphyseal measurements (radius, ulna, humerus) using peripheral Quantitative Computed Tomography (pQCT). - Methods: Fourteen males (age: 25.8±2.3 years,) underwent repeat pQCT scans (one to two days apart) at mid-shaft ulna (60%), mid-shaft radius (60%) and mid-shaft humerus (50%) cross-sections of the non-dominant limb. Intraclass correlation coefficients (ICC) and coefficients of variation (CV) were determined for musculoskeletal morphology variables. - Results: Reliability was excellent (ICC: 0.76–0.99; CV: 1.3– 7.3) at all sites for bone mass, stress-strain index, endocortical and pericortical radius, endocortical volumetric…
The reliability of measuring medial gastrocnemius muscle-tendon unit lengths during gait
2021
Background Ultrasound imaging combined with 3D motion analysis allows for in-vivo assessment of muscle-tendon unit lengths during gait. The clinical relevance of analysing the medial gastrocnemius (MG) and Achilles muscle-tendon junction (MTJ), MG mid-muscle belly fascicles (FAS) and muscle thickness was shown. However, their reliability error estimations over the gait cycle is unknown. Research question What are the intra- and inter-session errors associated with extracting MG belly, thickness, FAS and tendon lengths using ultrasound during gait in healthy participants? Methods 3D gait analysis was carried out in ten healthy adults as they walked on an instrumented treadmill at a comfortab…
Reliability and Validity of Family Affluence Scale (FAS II) among Adolescents in Beijing, China
2011
This study comprises two sub-studies. Study I assessed the test-retest reliability of Family Affluence Scale (FAS II) items among 95 students aged 11 and 15 years old in Beijing. Study II investigated the completion rate of traditional indicators (parents’ educational level, perceived family wealth, resident area, and school location) measuring socioeconomic status (SES) compared with FAS II, and examined the internal reliability, external and construct validity of the FAS II items in a population of 5876 schoolchildren aged 11, 13 and 15 years old in Beijing. Our study found that the FAS II items have high completion rates (> 99%) which are better than other SES indicators. Analyses of rel…
Item response theory and differential test functioning analysis of the HBSC-Symptom-Checklist across 46 countries
2022
Abstract Background The Symptom Checklist (SCL) developed by the Health Behaviour in School-aged Children (HBSC) study is a non-clinical measure of psychosomatic complaints (e.g., headache and feeling low) that has been used in numerous studies. Several studies have investigated the psychometric characteristics of this scale; however, some psychometric properties remain unclear, among them especially a) dimensionality, b) adequacy of the Graded Response Model (GRM), and c) measurement invariance across countries. Methods Data from 229,906 adolescents aged 11, 13 and 15 from 46 countries that participated in the 2018 HBSC survey were analyzed. Adolescents were selected using representative s…
Reliability and Validity Study of the Finnish Adaptation of Scoliosis Research Society Questionnaire Version SRS-30
2017
Study design A prospective clinical study to test and adapt a Finnish version of the Scoliosis Research Society 30 (SRS-30) questionnaire. Objective The aim of this study was to perform cross-cultural adaptation and evaluate the validity of the adapted Finnish version of the SRS-30 questionnaire. Summary of background data The SRS-30 questionnaire has proved to be a valid instrument in evaluating health-related quality of life (HRQoL) in adolescent and adult population with spine deformities in the United States. Multinational availability requires cross-cultural and linguistic adaptation and validation of the instrument. Methods The SRS-30 was translated into Finnish using accepted methods…
Construct validity and reliability of the physical activity parenting questionnaire for children (PAP-C)
2021
Background Children’s perception of parenting is hypothesised to significantly affect their physical activity (PA). This study aimed to examine construct validity, factorial invariance and reliability of a new tool: Physical Activity Parenting questionnaire for Children (PAP-C). Methods PAP-C comprised 22 items hypothesised to cover 3 theory-guided factors of physical activity parenting (PAP)—namely, structure for activity, autonomy support and involvement. Construct validity and internal consistency of PAP-C were tested using confirmatory factor analysis (CFA) and composite reliability in a sample of Finnish first, second- and third graders (n = 456; mean age 8.77 ± 0.84 years, girls 51.1%…
Psychometric properties of the 10-item Connor–Davidson resilience scale among Finnish older adults
2021
Objectives: Resilience, the ability to bounce back after adverse events may be an important factor in active aging. The 10-item version of the Connor–Davidson Resilience Scale (CD-RISC10) seems suitable for aging research owing to its low participant burden; however, its psychometric properties have not been comprehensively reported for older people. For example, no estimate exists of the test–retest reliability of the scale when used with older adults. Hence, this study evaluated the psychometric properties of the CD-RISC10 in a large population-based sample of community-dwelling older people. Method: The scale’s internal consistency, factor structure, construct validity, test-retest relia…
Reliability and validity of the Finnish version of the Visual Analogue Scale Foot and Ankle (VAS-FA).
2018
Background: There have previously been no validated foot and ankle-specific patient-reported outcome measures in Finnish. Methods: The Visual Analogue Scale Foot and Ankle (VAS-FA) was translated and adapted into Finnish. Thereafter, 165 patients who had undergone foot and ankle surgery completed a questionnaire set on two separate occasions. Analyses included testing of floor-ceiling effect, internal consistency, reproducibility, and validity. Results: Minor linguistic differences emerged during the translation. Some structural adjustments were made. The mean (SD) total VAS-FA score was 74 (23). In the three subscales, maximum scores were noted in 2-5% of the responses, and internal consis…
