“…Monotonicity was evaluated by graphing item characteristic curves depicting the relationships between IRT estimated fatigability scores and responses to each item. 19,35 Reliability (analogous to IRT information) of at least 0.70 was considered adequate for group comparisons. 36 Differential Item Functioning (DIF) analyses evaluated whether the items were free of measurement bias-that is, conditional on estimated fatigability, the probability of selecting each response option was not associated with other factors such as age, time since injury, level of injury (paraplegia or quadriplegia) or gender.…”

“…37 To avoid false positives due to multiple hypotheses testing we applied the Benjamini-Hochberg adjustment (P < 0.01). 31,35,[37][38][39] The magnitude of DIF was assessed using the weighted area between the curves (wABC) method, which measures the DIF effect size whilst accounting for the underlying distribution: for measurement items with four response categories, a wABC of 0.24 is considered non-negligible. 35,37…”

“…IRT is also useful in identifying other areas for improvement of a scale, such as item redundancy and poorly performing items. While IRT has been advantageous for confirming the psychometric soundness of many instruments, such as the Parenting Scale (Lorber, Xu, Slep, Bulling, & O'Leary, ), the Autonomy over Tobacco Scale (Wellman, Edelen, & DiFranza, ), and measures of teen dating violence attitudes (Edelen, McCaffrey, Marshall, & Jaycox, ), the technique is rarely applied to research on SOC. To our knowledge, only two previous studies (Coffman & BeLue, ; Prati, Cicognani, & Albanesi, ) have applied IRT to research on SOC, and no study to date has previously applied IRT to assess the psychometrics of measures of SOC‐R.…”

“…Nikotin bağımlılık düzeyi özellikle seçilecek tedavi yöntemi ve süresini belirlemede çok önemlidir (9). Bu nedenle çok farklı bağımlılık düzeyini ölçen ölçekler geliştirilmiştir (10,11,12,13). Bu ölçeklerden ülkemizde sigara bırakma kliniklerinde en sık kullanılanı FNBT'dir.…”
