The Italian version of the Obsessive–Compulsive Drinking Scale: validation, comparison with the other versions, and difference between type 1- and type 2-like alcoholics

Validation study of the Turkish version of the obsessive–compulsive drinking scale in male alcohol dependent inpatients / Obsesif–kompulsif içme ölçeğinin Türkçe şeklinin yatarak tedavi gören erkek alkol bağımlılarında geçerlilik ve güvenirlik çalışması

“…Turkish version of the both French (10 item) and Dutch (14 item) solutions were found to be compatible with (24) were both statistically significant, did not support the validity of grouping the score of four pairs of items and balancing the score range between OB and CP. This finding was consistent with the Italian study (21). Also the results of Schippers et al (23) were relevant for this conclusion, as they found the same validity for the original and the substituted versions of the scale.…”

“…Also regardless of the type of alcoholism, treatment seeking population were severely dependent population, which may all increase the probability of function impairment. Nevertheless, with respect to the findings of Janiri et al (21) in the Italian study, who identified three-factor solution, we can confirm the three-factor solution for the scale, but the resulting factors seemed to describe the scale as a whole with its original distinction into two groups of items as Janiri et al suggested in their population. The correlation between OB, CP and OCDS total score was high, as was expected from their association in the construction of the scale.…”

“…As in previous studies two different methods were used to calculate these three variables (23,24), both of them were followed in the Italian study (21) in order to compare their results with those of the Dutch (23) and French (24) research groups. We too used both calculation system and compared with all these three studies (21,23,24). In the Dutch method, sum scores of items 1 to 6 (maximum score: 24) is obsessive subscale (OB-D), whereas sum scores of items 7 to 14 (maximum score: 32) is compulsive subscale (CP-D).…”

“…Means ± S.D. (calculated according to the Dutch (D) and French (F) methods) and Cronbach's α values were compared to those found in the Dutch (23), French (24) and Italian studies (21). In alcohol dependents, the internal consistency coefficient (Cronbach's alpha) was (Table 6).…”

“…The widespread use of the OCDS can also be seen from the OCDS versions validated in other languages, e.g. French (19), Japanese (20) and Italian (21). Although the Turkish version of the YBOCS-hd proved to be a reliable and valid instrument measuring craving in alcohol-dependent male individuals (22), until now, validation study of OCDS in Turkish population had not been conducted.…”
