Testing the ruler with item response theory: Increasing precision of measurement for relationship satisfaction with the Couples Satisfaction Index.

“We recommend that future large epidemiological studies consider a more recently developed, but brief, four-item Couples Satisfaction Inventory that was developed empirically based on item analyses of the most commonly used marital quality measures (Funk & Rogge, 2007).”

“Participants with children also answered a modified version of the Couples Satisfaction Inventory–4 in regard to their satisfaction with their relationship with their children.”

“Data collected from the following relationship satisfaction measures were included: the Couple Satisfaction Index (CSI; Funk & Rogge, 2007), the Daily Dairy of Relationship Quality (DDRQ;Hemphill, 2013), theDyadic Adjustment Scale (DAS; Spanier, 1976), the Marital Happiness Rating Scale (MHRS;…”

“Given this, we recommend that future researchers use newly available global measures of satisfaction derived from Item Response Theory analyses (Funk & Rogge, 2007) that are far more reliable than older adjustment or global satisfaction measures (Rogge, Funk, & Lee, 2009).”

“Using classical test theory and IRT, Funk and Rogge (2007) set out to increase the precision of measurement in the field by analyzing an item pool of 180 items representing eight widely used measures of marital satisfaction, including the DAS and MAT.”

“First, relationship problems can be stressful, particularly if they are severe and/or chronic in nature; measures of marital adjustment are highly correlated with perceived stress (Funk and Rogge 2007).”

“In the third step, after establishing the two-factor structure of the AIR Scale, we examined its convergent and discriminant validity using two additional samples.”

“We assessed relationship satisfaction using Funk and Rogge’s (2007) four-item measure (e.”

“As with the concerns raised by the noise in measurement of the MAT and DAS, only time will reveal how forcing negative and positive evaluations onto a single scale might have obscured many potentially interesting and informative results.”

“Psychometrically sound and theoretically coherent instruments for assessing marital satisfaction are in wide use (e.g., Funk & Rogge, 2007).”

“34], and neither test was significant after controlling for covariates [χ(2)(10) = 14.”

“The measure correlated with standard relationship assessments in a large sample of dating and married participants (Funk & Rogge, 2007).”

“Specifically, we used four items from the couple satisfaction index (Funk & Rogge, 2007) to form the construct of relationship quality: satisfaction (from 1 = worse than all others/extremely bad to 6 = better than all others/extremely good ), reward (from 1 = not at all to 6 = very much or…”

“This criticism of multiple component marital assessments has been endorsed by later research (e.g., Fincham & Linfield, 1997; Fincham & Rogge, 2010; Funk & Rogge, 2007; Weiss, 2005).”

“At baseline, 8 weeks postbaseline, and approximately 10 months (44 weeks) postbaseline, participants completed questionnaires that assessed symptoms of depression and anxiety (i.e., Beck Depression Inventory, Beck, Steer, & Garbin, 1988; Beck Anxiety Inventory, Beck, Epstein, Brown, & Steer, 1988), intimate partner vi…”

“Starting with 180 items previously used to assess relationship satisfaction, Funk and Rogge (2007) conducted an item response theory analysis to develop a 4-item measure of relationship satisfaction with optimized psychometric properties.”

“This is consistent with recent findings that IRT (when used in large samples with large and diverse item pools) can offer a powerful method of optimizing measures (e.g., Funk & Rogge, 2007; Fraley et al., 2000).”

“Single-item questions were used to assess couple satisfaction (from Couple Satisfaction Index; Funk & Rogge, 2007; see Rhoades, Stanley, & Markman, 2012a for similar assessment), personal commitment, perceived partner commitment (similar to standard, multi-item measures of dedication commitment;…”

“Fourth, although there is evidence that the total score from the Dyadic Adjustment Scale has similar psychometric properties for gay, lesbian, and heterosexual partners (Kurdek, 1992), statistical evidence for stronger forms of measurement invariance—such as factor loading and intercept invariance (Widaman & Reise, 19…”

“…Scale-5 (CAPS-5; Weathers et al., 2013a) was used as the clinician-rated primary outcome measure of PTSD symptoms, and the PTSD Checklist (PCL-5, patient and partner versions; Weathers et al., 2013b) and Couples Satisfaction Index (CSI; Funk & Rogge, 2007) were used as self-report primary outcomes.”
