“…Similar conclusions have been reported with regard to both test-retest reliability and internal consistency via simulation (e.g., Jenkins & Taber, 1977) and using empirical data (e.g., Chang, 1994;Maydeu-Olivares et al, 2009;Preston & Colman, 2000;Weng, 2004). Previous studies have also shown that increasing binary response formats to a 4-point rating scale improves reliability (Cox et al, 2012;Cox et al, 2017;J. H. Finn et al, 2015).…”

“…Similarly, in the assessment of personality and other individual differences, Maydeu-Olivares et al (2009) found a slight increase in the average correlations between the target scale score and 11 external questionnaire scores; however, there was no evidence to suggest that increasing the number of scale points improved validity. More recently, findings in a number of studies indicate that although increasing the number of response categories could improve the reliability of scale scores, improved reliability did not improve convergent validity (Courrégé & Weed, 2019;Cox et al, 2012;J. H. Finn et al, 2015;Simms et al, 2019).…”

Revisiting the Effect of Varying the Number of Response Alternatives in Clinical Assessment: Evidence From Measuring ADHD Symptoms

et al. 2020

This study illustrated the effect of varying the number of response alternatives in clinical assessment using a within-participant, repeated-measures approach. Participants reported the presence of current attention-deficit/hyperactivity disorder symptoms using both a binary and a polytomous (4-point) rating scale across two counterbalanced administrations of the Current Symptoms Scale (CSS). Psychometric properties of the CSS were examined using (a) self-reported binary, (b) self-reported 4-point ratings obtained from each administration of the CSS, and (c) artificially dichotomized responses derived from observed 4-point ratings. Under the same ordinal factor analysis model, results indicated that the number of response alternatives affected item parameter estimates, standard errors, goodness of fit indices, individuals’ test scores, and reliability of the test scores. With fewer response alternatives, the precision of the measurement decreased, and the power of using the goodness-of-fit indices to detect model misfit decreased. These findings add to recent research advocating for the inclusion of a large number of response alternatives in the development of clinical assessments and further suggest that researchers should be cautious about reducing the number of response categories in data analysis.

“…For instance, it has been noted that copyright issues have prevented researchers from improving the items in many proprietary scales, such as the NEO-PI-R, by the use of item response theory (Reise & Henson, 2003). For example, Cox et al (2012) demonstrated that by increasing the number of item categories in the MMPI-2 scales (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) from two to four, coefficient alpha was substantially improved across nearly all these scales. Many proprietary scales still employ dichotomous or trichotomous response scales, but even a simple alteration in the number of item categories is typically prohibited for proprietary scales.…”

A Meta-Analysis of the Reliability of Free and For-Pay Big Five Scales

The present study meta-analytically compared coefficient alpha reliabilities reported for free and for-pay Big Five scales. We collected 288 studies from five previous meta-analyses of Big Five traits and harvested 1,317 alphas from these studies. We found that free and for-pay scales measuring Big Five traits possessed comparable reliabilities. However, after we controlled for the numbers of items in the scales with the Spearman-Brown formula, we found that free scales possessed significantly higher alpha coefficients than for-pay scales for each of the Big Five traits. Thus, the study offers initial evidence that Big Five scales that are free more efficiently measure these traits for research purposes than do for-pay scales.

“…Several past studies also dichotomized suicide risk as present or absent (e.g., Harris et al, 2009b;Mitchell & Ybarra, 2007;Reynders, Kerkhof, Molenberghs, & Van Audenhove, 2014). However, dichotomizing predictor variables or outcomes reduces validity by limiting the amount of information available on the latent trait and should thus be avoided (Cox et al, 2012;Markon, Chmielewski, & Miller, 2011;Royston, Altman, & Sauerbrei, 2006). Others have used continuous measures of both help seeking and suicidality, as well as including a variety of help sources, providing greater depth and validity to their findings (e.g., Deane et al, 2001;Yakunina et al, 2010).…”

Offline Versus Online Suicide-Related Help Seeking: Changing Domains, Changing Paradigms

These findings show that the Internet has altered the suicide-related help-seeking paradigm. Online help seeking for suicidality was not more popular than face-to-face help seeking, even for emerging adults. However, treatment and prevention professionals have good reasons to increase their online efforts, because that is where some of the highest risk individuals are going for help with their most severe personal problems.
