“…17,18 Thus, the minimum sample size required for sound factor analysis is 290 subjects which is near what Comrey and Lee 19 suggested as a good sample size. This study has a sample size of 410 which exceeds the cited requirement in the literature.…”

* Background: Pharmacy value added services (PVAS) was introduced as a matter of public health policy by Malaysia's Ministry of Health to improve health outcomes through public healthcare services. For example, drive through pharmacy services is a major policy implementation of the Ministry. However, adoption rates are low and therefore hampering the achievement of national health policy goals. Objective: Our objective is to explore the key determinants and mediators of successful implementation of new public pharmaceutical services by investigating the cognitive perspectives of patients' intentions to adopt with the Theory of Planned Behavior as the theoretical framework. Methods: A two phase mixed methodology involving first a qualitative exploration and the second a quantitative phase was conducted in public health facilities in Negeri Sembilan, Malaysia. Multiple regression and mediation analysis were performed. Results: Subjective norms, perceived behavioural control, knowledge and expectations are found to be significant predictors of intentions to adopt PVAS. Knowledge and expectations are found to exert significant indirect effects on intentions. Conclusion: Overall, we suggest that patient knowledge be enhanced through appropriate channels and expectations of service quality be met to increase intentions.

“…Örneklem büyüklüğüne ilişkin çeşitli çalışmalar, farklı sayı ve oranlar önermektedir (MacCallum, Widaman, Zhang & Hong, 1999). Ancak birçok çalışma, AFA için en uygun sayının 300 olduğunu ifade etmektedir (Field, 2009;Kass & Tinsley, 1979;Tabachnick & Fidell, 2000). Bunun yanında, bazı çalışmalar da örneklem büyüklüğünün madde sayısı ile orantılı olduğunu öne sürmektedir.…”

Öz: Bu çalışmada bilişim teknolojileri (BT) öğretmen adaylarının çevrimiçi sosyal ağları (ÇSA) öğretim amaçlı kabul ve kullanım süreçlerine ilişkin bir ölçek geliştirilmiştir. Geliştirilen ölçeğin kuramsal çerçevesini teknoloji kabul modellerinden "Teknoloji Kabul ve Kullanım Birleştirilmiş Model"i oluşturmuştur. Açımlayıcı faktör analizi (AFA) için 302, doğrulayıcı faktör analizi (DFA) için 210 olmak üzere üç farklı devlet üniversitesinin Bilgisayar ve Öğretim Teknolojileri Eğitimi (BÖTE) bölümü öğrencilerinden veri toplanmıştır. Analizler sonucunda 36 maddeden oluşan dört faktörlü bir yapı ortaya konmuştur. ÇSA'ları öğretim amaçlı olarak kabul ve kullanım durumlarının performans beklentisi, çaba beklentisi, sosyal etki ve kullanma niyetlerinden etkilendiği sonucuna ulaşılmış; bu dört faktör toplam varyansın %67,02'sini açıklamış, yüksek bir iç tutarlılık katsayısı sergilemiştir (α=.97). Dört faktörlü bu yapıya ilişkin DFA sonucunda da kabul edilebilir uyum değerlerine ulaşılmıştır (RMSEA= 0.075; SRMR=0.080; NNFI= .094; CFI= .094; α=.93). Ölçekten alınan yüksek puan, BT öğretmen adaylarının ÇSA'ları öğretim amaçlı kabul durumlarının ve mesleki yaşamlarında kullanma eğilimlerinin yüksek olduğuna işaret etmektedir.Anahtar Kelimeler: Bilişim teknolojileri, çevrimiçi sosyal ağlar, yeniliklerin kabulü, teknoloji kabul ve kullanım birleştirilmiş modeli DOI: 10.16949/turkbilmat.298120 Abstract:The current study aimed to develop a scale to address the acceptance and use of online social networking sites (SNSs) for instructional purposes among information technology teachers. The theoretical framework of the scale was based on The Unified Theory of Acceptance and Use of Technology (UTAUT). Data were collected from computer education departments of three state universities to conduct an exploratory factor analysis (n: 302) followed by a confirmatory factor analysis (n: 210). Analyses revealed a four-factor structure which sheltered 36 items. It was observed that acceptance and use of SNSs for instructional purposes were composed of performance expectancy, effort expectancy, social influence and behavioral intention, which explained 67.02 percent of the total variance with a high internal consistency coefficient (α=.97). The confirmatory analysis on the four-factor structure revealed acceptable fit indices as well (RMSEA= 0.075; SRMR=0.080; NNFI= .094; CFI= .094; α=.93). Higher scores from the scale can be interpreted as higher acceptance rate and tendency to use SNSs for instructional purposes.Keywords: Information technologies, online social networks, acceptance of innovations, the unified theory of acceptance and use of technology See Extended Abstract GirişGünümüzde bilgi ve iletişim teknolojileri (BİT) sağlık, ekonomi, e-devlet uygulamaları ve iletişim gibi farklı alanlarda yoğun bir biçimde kullanılmaktadır.

“…This resulted in a sample size of 320 complete observations available for factor analysis procedures. This sample size of 320 was adequate to conduct factor analytic procedures 36,37 and offered a case-to-item ratio of approximately 6:1 for Part 1 and a case-to-item ratio of approximately 7:1 for Part 2 of the questionnaire. As an added check, the factor analyses were performed on the smaller sample of 230 with no imputed values for missing data.…”

BACKGROUNDThis study was conducted to evaluate a self‐administered questionnaire developed to measure the needs experienced by men diagnosed with prostate carcinoma (the Prostate Cancer Needs Questionnaire [PCNQv1.1]). The PCNQv1.1 was constructed in two parts. Part 1 measures the needs at diagnosis and initial treatment and Part 2 measures current needs.METHODSA random sample of 650 men diagnosed with prostate carcinoma who were being treated by a urologist of the Hunter Urology Group in Newcastle, New South Wales, Australia, were invited to participate in the study. They were sent by post the self‐administered PCNQv1.1. Completed questionnaires were received from 385 men. Information provided on 100 additional men was considered ineligible.RESULTSThe principal components method of factor analysis with varimax orthogonal rotation identified eight factors with eigenvalues greater than 1, which accounted for 61.7% of the variance in Part 1 of the PCNQv1.1. Likewise, six factors were identified in Part 2, which accounted for 63.5% of the variance. Internal reliability coefficients (Cronbach alpha) were adequate for identified factors with values ranging from 0.70 to 0.88 for Part 1 and from 0.71 to 0.87 for Part 2. Test‐retest reliability was acceptable with intraclass correlation coefficients ranging from 0.61 to 0.78 for Part 1 and from 0.60 to 0.82 for Part 2.CONCLUSIONSThese results suggest that the PCNQv1.1 is a valid and reliable instrument to assess the needs experienced by men diagnosed with prostate carcinoma.
