    (Kılıçhan Bayar, 30 Nisan 2024) Birinci, Tansu; Veer, Pınar Van Der; Kolbaşı, Esma Nur; Altun, Süleyman; Ergin, Ömer Naci
    Objective: The present study aimed to identify the clinical variables influencing perceived pain intensity at rest, during activity, and at night in female patients with knee osteoarthritis (OA). Method: One hundred-six female patients with knee OA (mean age, 58.50±9.48 years; mean BMI, 30.73±5.53 kg/m2) were included. The Visual Analogue Scale (VAS), active range of motion (AROM), strength of the iliopsoas, gluteus medius, quadriceps femoris, and hamstring muscles, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Short Form-12 (SF-12) were outcome measures. A multivariate or univariate regression analysis was conducted to examine the relationship between the VAS ratings and AROM, muscle strength, WOMAC, SF-12, and Kellgren-Lawrence classification. Results: The mean values for VAS-rest, VAS-activity, and VAS-night were 3.02±2.32, 6.62±1.96, and 3.89±2.72, respectively. A significant correlation was found between VAS-rest and quadriceps femoris muscle strength, as well as the WOMAC score. Similarly, VAS-activity showed a significant association with hip flexion and knee extension AROM, quadriceps femoris muscle strength, Grade 3 or Grade 4 OA, physical component score of SF-12, and WOMAC score (p<0.05). There was also a significant association between VAS-activity and age (β:-0.194, 95%CI:-0.043 - 0.021, p=0.04). Conclusion: The quadriceps femoris muscle strength and functional level of the patients with knee OA significantly predict both pain intensity at rest and during activity. In addition, pain intensity during activity was found to be associated with hip flexion and knee extension AROM, Kellgren-Lawrence grading, the physical component of quality of life, and age.

    The reliability and validity of the Turkish version of smartphone impact scale
    (SAGE Publications Inc., 2022) Birinci, Tansu; Van Der Veer, Pınar; Mutlu, Caner; Mutlu, Ebru Kaya
    The Smartphone Impact Scale (SIS) was originally developed in English to determine the cognitive, affective, social, and behavioral impacts of smartphones. This study aimed to translate and cross-culturally adapt the SIS instrument into Turkish and investigate its psychometric properties. Two hundred and sixty-four young and middle-aged adults (186 females) with a mean age of 36.24 years (SD = 14.93; range, 18–65 years) were included. For cross-cultural adaptation, two bi-lingual translators used the back-translation procedure. Within a 5-to-7-day period after the first assessment, the participants completed the Turkish version of SIS (SIS-T) to evaluate test-retest reliability. Cronbach’s alpha (?) was used to assess internal consistency. The correlation between the Turkish version of the Smartphone Addiction Scale (SAS-T) and the Nottingham Health Profile was determined to check the validity. The SIS-T had a high-level internal consistency (? = 0.86) and test-retest reliability (ICC2,1 = 0.56 to 0.89 for subscales). The SIS-T subscales were correlated with the SAS-T (r = 0.31 to 0.66, p < 0.01), indicating a good concurrent validity. The results show that the SIS-T is semantically and linguistically adequate to determine smartphones' cognitive, affective, social, and behavioral impacts on young and middle-aged adults. Good internal validity and test-retest reliability of the SIS-T were defined to evaluate the impacts of smartphones among Turkish-speaking young and middle-aged adults. © The Author(s) 2022.

    The Validity and Reliability of the Turkish Version of Self-Perceived Barriers for Physical Activity Questionnaire
    (Sage Publications Inc, 2023) Kolbasi, Esma Nur; van der Veer, Pinar; Birinci, Tansu
    Identifying the barriers to physical activity (PA) is important for comprehensive management strategies to decrease physical inactivity. This study aimed to translate and cross-culturally adapt the Self-Perceived Barriers for Physical Activity Scale (SPBPA) into Turkish and investigate its psychometric properties. One-hundred fifty-two young and middle-aged adults (mean age of 33.3 & PLUSMN; 12.66 years) were included. Within a 5-to-15-day period after the first assessment, the participants completed the Turkish version of SPBPA (SPBPA-T) to evaluate test-retest reliability. Cronbach's alpha (& alpha;) was used to assess internal consistency. The correlation between the SPBPA-T and Physical Activity Barriers Questionnaire (PABQ) and Short Form-12 (SF-12) was determined to check the validity. The SPBPA-T had a strong internal consistency (& alpha; = .83) and test-retest reliability (ICC2,1 = .90). There was a strong correlation between PABQ and SPBPA-T (r = 0.709; p < .0001), indicating strong construct validity. The convergent validity of SPBPA-T was confirmed with the mental component of SF-12 (r = -.228; p < .0001). There was no floor or ceiling effect. The questionnaire had a 1.083 SEM value and its MDC was 3.00 points. The SPBPA-T is semantically and linguistically adequate and has strong internal validity and test-retest reliability to determine the self-perceived barriers to PA among Turkish-speaking young adults.
