“…Örneklem sayısının genellikle 301-500 arasında tutulması geçerlik ve güvenirlik açısından olumlu olmakla birlikte daha güvenilir sonuçlar elde etmek adına örneklem sayısının daha da artırılması gerekli görülmektedir. Zira Comrey ve Lee (1992), örneklem büyüklüğü için gerekli sayının 100= zayıf, 200= orta, 300=iyi, 500= çok iyi ve 1000= mükemmel olarak nitelendirirken; Aleamoni (1976) alt sınırın 400 olması gerektiğini ifade etmiştir. Ayrıca bu çalışmada AFA analizlerinde de faktör başına düşen kişi sayısı ölçütüne yönelik katılımın düşük düzeyde olması ve Tosun ve Taşkesenligil (2014) tarafından ölçek geliştirme çalışmalarında kullanılan örneklem büyüklüğünün genel olarak 101-200 kişi arasında değiştiğine yönelik elde edilen bulgular, Türkiye'de ölçek geliştirme çalışmalarında örneklem büyüklüğü açısından güvenirlik konusunda bir zayıflığın olduğunu düşündürebilir.…”

A AB BS S T TR RA AC CT T O Ob bj je ec ct ti iv ve e: : This study was conducted to develop the Reproductive Health Scale (RHS) as a valid and reliable measure of adolescents' reproductive behavior. M Ma at te er ri ia al l a an nd d M Me et th ho od ds s: : Data were collected using self-report method from 320 students, aged between 17 -30 years. Two questionnaires were used in this research: a socio-demographic data form and RHS, developed by the researchers. Kendall coefficient of concordance (W) was used for RHS' content analysis, and stability over time (test-retest reliability) and Pearson product moment correlation coefficient were used for its reliability analysis. In addition, internal consistency, Cronbach alpha calculation, Item to total score correlation technique, split-half and Spearman-Brown reliability coefficients were also calculated. R Re es su ul lt ts s: : Exploratory principal components' analysis with varimax rotation yielded 34 items consisting of six factors: Partner selection, values in developing protective behavior, consultation, communication with sexual partner, confidence and protection from sexually transmitted diseases, accounting for 48.5% of the variance. Alpha reliability was 0.88; factor reliabilities ranged from 0.55 to 0.84. It was concluded that the adolescents who responded to the scale had more positive attitudes in reproductive health as their scores increased. C Co on nc cl lu us si io on n: : The results of this study determined that this scale was highly reliable. It is suggested that the scale can be used in reproductive health studies carried out with adolescents and in their education in order to determine their statuses and also its validity and reliability analyses can be performed by applying it to different groups.K Ke ey y W Wo or rd ds s: : Reproductive medicine; adolescent health services; attitude; reproducibility of results Ö ÖZ ZE ET T A Am ma aç ç: : Bu çalışma adolesanların üreme davranışı için geçerli ve güvenilir bir ölçü olarak üreme sağlığı ölçeğini (ÜSÖ) geliştirmek için yapıldı. G Ge er re eç ç v ve e Y Yö ön nt te em ml le er r: : Veriler yaşları 17 ile 30 arasında olan 320 öğrenciden kişinin kendi beyanına dayalı rapor yöntemi ile toplandı. Bu araştırmada iki anket kullanıldı: Sosyo-demografik veri formu ve araştırmacılar tarafından geliştirilen ÜSÖ. ÜSÖ'nün içerik analizi için Kendall uyuşum katsayısı (W) ve güvenilirlik analizi için zaman içinde tutarlılık (test-tekrar test güvenilirliği) ve Pearson momentler çarpımı korelasyon katsayısı kullanıldı. Ayrıca iç tutarlılık, Cronbach alfa katsayısı, madde/toplam puan korelasyon tekniği, ikiye bölme (Split-half) ve Spearman-Brown güvenilirlik katsayıları da hesaplandı.

“…The next task is to select the minimum sample size for data collection. Some studies consider a range between 50 to 400 as minimum sample size (Aleamoni, 1976). Therefore, in order to cross the minimum sample size requirement 150 randomly selected bank managers and other credit officers will be selected in the province of Punjab and city Lahore.…”

The Non-Performing loans presented picture of a distorted and slow-paced economy. This issue became more critical when it was observed that NPLs were declining in South East countries except for Pakistan. This study has dual purposes: Firstly to build up a model clarifying the relationship between bank-specific, social factors and non-performing loans. Secondly, to investigate this model in the setting of Pakistani Banking sector as limited interest has been given in existing literature in defining the relationship between bank specific, social factors and non-performing loans. The quantitative methodology is used as it is the most suitable for fulfillment of the study objectives. The results show that various bank-specific factors like credit assessment, credit monitoring and rapid credit growth have significant affect on Non-Performing Loans, whereas interest has a weak significance on NPLs. The social factors including political interference and bankers' incompetence have significant affects on NPLs and these have been important factors in explaining the NonPerforming Loans. This ground-breaking work on Non-Performing Loans and its factors will not only help the entire Pakistani banking sector to control Non-Performing Loans but also its results can be generalized on other countries as well.
