Nevertheless, there is no denying that remembering anniversaries, breakfast in bed and little affectionate gifts can contribute to a lasting romance, maintenance of passion and feeling of being loved, which in turn have a major impact on relationship satisfaction Bradbury et al. Some people prefer complete independence from their partner, while others rely on their partner for almost everything, from self-worth to personal identity to decision making.

There are those who need independence, and others who prefer to be attached at the hip most of the time. Differentiation of self in intense emotional bonds is essential for development of a healthy relationship. It allows for greater role flexibility and deeper intimate contact. The TCT also assesses other issues that are related to attachment style and dependency problems, such as security in a relationship and jealousy.

Fear of rejection and abandonment are commonplace in couples with attachment problems. Research by Downey and Feldman shows that rejection-sensitive people and their partners experience dissatisfaction with their relationship. In addition, the TCT includes several subscales that assess need for personal space i.

For example, people with dysfunctional relationship cognitions think that successful couples should never have any disagreements, should want to spend all their free time together or should never be attracted to another person. They feel that people who love each other should not have any secrets, should not need any personal space, should share anything and everything and should not need any friends other than their partner. A relationship has the potential to be a great source of support in stressful time — yet, for those people that deal poorly with stress the potential deterioration of the relationship can only add more stress.

In addition, negative stressful events during workday contribute to angry marital behavior in women and withdrawal in men Schulz et al. According to Larson and Richards , minor daily stressors, such as chores, childcare, and errands have a major effect on the emotional lives of the partners and the nature of family relationship.

Brody argued that marriage is one context in which women are more likely to express more anger than men. These gender differences appear to be more pronounced under stress. In a study by Waldinger et al. Therefore, the TCT includes an assessment of emotional intelligence. The Psychological Strength subfactor includes several aspects that address these issues: There is no doubt that dealing with unstable emotions in a partner is difficult, often leading to marital problems. However, the relationship between depression and marital distress is bi-directional.

In addition, neuroticism in one of the partners has been shown to be one of the best predictors of marital distress and dissolution of the couple Kurdek, Negative emotional behavior e. Likwise, self-esteem has been shown to be a good predictor of relationship satisfaction, especially in men Bailey et al. Technical Quality of the TCT. The Rasch model is increasingly used for other purposes as well for an overview, see, e. The standard error of measurement differs between persons with different response patterns but generalizes across populations. Shorter tests can be more reliable than longer tests.

Comparing tests forms across multiple forms is optimal when test difficulty levels vary across persons. Unbiased estimates of item properties may be obtained from unrepresentative samples. In other words, the classical notion that all test scores are equally reliable is abandoned in favor of local i. In the extreme, items can be selected specifically to optimize reliability or, equivalently, minimize SE.

The Rasch scaling of binary i. For binary items i and persons n:. In the above, P ni reflects the probability that person n will answer item i affirmatively, where person n has trait level B n and item i reflects the trait amount D i. Note that the item and person parameters share a common metric as defined by the left-hand side of Equation 1 — i. Accordingly, all quantities in the Rasch model are said to be expressed in logits.

Equation 1 shows that the Rasch model is additive in the parameters B n and - D i. Thus, in contrast to related models such as the two- and three-parameter logistic cf. Accordingly, raw scores are sufficient statistics for the parameters B and D — indeed, these quantities can be estimated independently of each other.

The Rasch model has been extended to rating scales Andrich, and partial-credit observations Masters, for polytomous items, i. To be precise, each F k reflects the point at which the choices of categories k and k-1 are modeled to occur with equally probability. However, they differ with respect to the assumptions made concerning the item-dependency of the step values.

In other words, it is assumed that items share the same step values within a particular sub-group, but these values are allowed to differ from the step values for other item sets. Like the item and person parameters, the step values are additive, thus yielding the hybrid model:. Solving for P nik in Equation 2 not shown, see, e. In this figure, F g1 and F g2 are shown at —1 and 0, respectively, as their values i.

Going from left to right, the curves in this figure reflect the probability of observing a particular rating 0, 1, 2, 3, given B. It is noted that the rating-scale and the partial-credit formulations are both special cases of Equation 2. The former obtains when all items are in the same group, and the latter obtains when each item defines its own separate group. Also, Equation 1 for binary items obtains when rating scales with just two categories are used.

Note that the additive properties of the model are maintained. Practice indicates that the model is robust against many forms of misfit, and typical perturbations in data tend to have little influence on the measure estimates. Thus, while a few misfitting items may introduce noise, the quality of measurement provided by the other items is thereby little affected. A further feature of the data is its robustness against missing data. There is no need to impute missing data, or to assume a particular form of the distribution of parameters. Of course, missing data decrease the precision with which parameters can be estimated.

In estimating the measures, the model acts as though the randomness in the data is well behaved in accordance to the particular Rasch model being used. This is not a blind assumption, however, because the quality control fit statistics can be computed to report where, and to what extent, this requirement has not been exactly met. For instance, for each response to item i by person n, a standardized residual z ni can be computed as the difference between an observed datum and the probability estimate P of its occurrence e.

Since such z s are approximately normally distributed, unexpected results e. The preceding forms the basis for computing the overall fit of the questions across respondents as quantified by their Outfit. For instance, the Outfit of item i over respondents n is:. Although the ideal Infit and Outfit values are 1, consistent with prevailing practice see e.

Note that fit values exceeding 1 indicate the presence of unmodeled variation i. The former is a more serious threat to model fit than the latter. Differential Item and Test Functioning. Recomputing the item locations B i in samples from this population can check this assumption. In the present context, age and gender are of particular interest because Lange, Houran et al.

The finding of DIF threatens construct validity since this implies that different sub-groups assign different semantics to the underlying variable for a discussion, see Lange et al. The presence of DIF does not imply however that the measurement of the latent variable is thereby seriously compromised — i. In particular, DIF in some items may cancel that in others, thereby having little or no effect on the estimated person parameters for examples see e. An effective means to establish the absence of DTF is to determine whether the raw-score to Rasch R-to-R measure conversions differ by more than these measures standard errors of measurement.

In the present research this is done graphically by a plotting the R-to-R translation, together with the local SE B i. The parameters of the Rasch models used here will be estimated using the versatile Winsteps software Linacre, These procedures are sufficiently efficient to analyze thousands of respondents and items simultaneously, while allowing group-specific rating scale parameterizations of the items.

Winsteps also computes the item-total correlations and the frequency of the ratings obtained for each item, as well as the Infit and Outfit statistics discussed above. A basic assumption underlying all of the preceding is that the items under consideration define a single latent dimension. Unfortunately, it has long been known cf. Comrey, ; Panter et al. Stout, , how multidimensionality may result from DIF — a finding that was confirmed by computer simulations Lange, Irwin et al.

The Winsteps software referred to above incorporates such factor analyses as well. Within classical test theory " The reliability of any set of measurements is logically defined as the proportion of their variance that is true variance We think of the total variance of a set of measures as being made up of two kinds of variance: The true measure is assumed to be the genuine value of whatever is being measured " Guilford, , p.

Thus, reliability as embodied for instance in the KR or coefficient alpha is not an index of quality of the instrument over which it is computed, but this index rather quantifies the extent to which scores can be reproduced. The major problem with the preceding definition is that it:. However, by explicitly modeling the stochastic nature of each data point X ni Rasch scaling can identify the source of the error variance. For instance, for the binary case,. The error variance of Rasch measures can thus be estimated by taking into account the sum of the modeled variance of observations.

Of course, this "model" error variance requires the data to conform stochastically to the Rasch model. Accordingly, Rasch reliability indices tend to be lower than KR and coefficient alpha. Equation 7 further implies that these indices always exceed the maximum reliability, thus indicating that a test has better measurement characteristics than it actually has. To be sure, KR and coefficient alpha accurately reflect the reliability of raw scores.

However, raw scores are not trait measures, but rather local, test-dependent rankings, and generalizing raw scores to test-independent, generalizable measures is simply not justified. Item and Person Reliability.

Although this is rarely done within the framework of classical test theory, the above applies equally to items and respondents. Thus, two types of reliability can be distinguished:. In addition to providing an impression of the adequacy of the size of the calibration sample, the latter is important in situations where items are selected based on their locations on the latent Rasch dimension e.

Item and Person Separation. While reliability indices are widely used, their interpretation is hindered by the fact that reproducibility is not a direct function of their magnitude. For instance, the difference between the two reliability coefficients 0. For this reason, in Rasch scaling contexts the item and person reliability coefficients R are often expressed as separability indices G:. The advantage of using G rather than reliability indices is that they directly reflect the number of statistically different performance strata that the test can successfully identify within a particular sample.

The rationale for this definition is that the functional range of typical measures is around 4 True SD. In most cases, it is reasonable to inflate this by 1 RMSE to allow for the error in the observed measures. In this context we note that Standard 2. As measures become increasingly extreme, then the density of the step values must eventually decrease. Hence, the standard error SE B associated with extreme i. Additional plots based on actual data will be given in Section 4 below.

This sample comprised men and women with a mean age of F emale ] — was: Regardless of their fit to the Rasch model or lack thereof , no respondents were excluded from the analyses. Similar analyses were then performed over the items in the seventeen most important subscales. For reasons that were discussed in the introduction, we identify the items as well as the subscales by numeric tags only. Except for one item Item 65 , all Outfit values fall within the standard acceptable range i. Also, just 5 of the items show negative Item-Total correlations.

Accordingly, it is meaningful to consider additional factors. The seventeen factors studied next were labeled as Factors 10, 18, 19, 29, 35, 42, 52, 71, 72, 73, 75, 76, 82, 84, 85, 88, and It can be observed that the items show excellent fit to the Rasch model, as indicated by the acceptable Outfit values and positive Item-Total correlations with very few exceptions, as is indicated by boldface entries. Accordingly, the internal structure of these factors supports the assumption that the items indeed define a latent dimension in accordance with the scaling assumptions of the Rasch model.

The results are shown pair wise in Figures 4 through 37 i. Given the absence of DTF , the error bands in Figures 4 through 37 may be assumed to give accurate estimates of the local SE B for each of the factors. In addition, for each of the seventeen factors Table 19 lists the Rasch reliability indices as well as the separation values G for the items as well as the respondents.

As was noted earlier, the person reliability corresponds most closely to the reliability estimate provided by Coefficient Alpha or KR within the framework of classical test theory. However, due to the more realistic error assumptions being made, the value of the Rasch reliability coefficients tends to be lower than overall reliability estimates obtained within the classical framework. Item and person Reliability and Separation G estimates.

Note that the Rasch reliability coefficients of the person measures produced by some of the subscales are rather small e. It should be kept in mind, however, that these subscales are not used in isolation, but rather that these contribute jointly to the matching process. Also, within the TCT matching algorithm, less reliable subscales do not form the decisive piece of information to match two individuals. Not surprisingly given the sample size, the reliability of the item locations is considerable.

Thus, their locations are known with high precision, thereby providing a sound basis for future expansion of the TCT. To assess the predictive validity of the TCT a separate study using married individuals, including couples was conducted Lange Houran et al. This study is described in its entirety in Appendix D of the online Manual. However, we summarize the major findings below.

  • This correlation rises to 0. Note that this effect size exceeds the validity findings reported by Wilson and Cousins for the WRCI measure of compatibility. Thus, there is solid evidence that couple similarity is associated with greater marital satisfaction.

    Of course, it is equivalent to say that those Low in satisfaction are particularly dissatisfied with these issues. Although direct evidence is lacking, we hypothesize that this is because differences in personal values are difficult to resolve by behavioral accommodation. Specifically, those most satisfied in their marriages report the lowest complementarity with their partners with respect to spending and saving money. However, respondents in the Low satisfaction group report maximum lack of complementarity with respect to sexual issues and parenting.

    In other words — and perhaps not surprisingly so — dissatisfaction in marriage quickly manifests itself as a lack of complementarity with respect to sexual and parenting issues. High satisfaction translation functions. Interestingly, the estimated person measures R r for a raw sum score of 24 1.

    Thus, the satisfaction related item-shifts are sufficiently large to introduce measurement distortions at the ordinal level as well. Moreover, statistical theory Stout, and computer simulations alike Lange et al. Accordingly, it is no longer obvious that widely cited results within the literature of assortative mating historical or current should be accepted at face value. For example, it seems likely that the notion of love consisting to varying extents of Romantic Dependency, Communicative Intimacy, Physical Arousal, Respect, and Romantic Compatibility Critelli et al.

    Finally, as is important for the increasing popularity of online matchmaking businesses, we note the findings of qualitative differences cast serious doubts on simple formulaic prescriptions for romantic compatibility and relationship success cf. The applicable Validity and Reliability Standards are shown separately in Tables 20 and 21, respectively.
