Is there more to complicated grief than depression and posttraumatic stress disorder? A test of incremental validity

There is growing interest in complicated grief reactions as a possible new diagnostic category for inclusion in the Diagnostic and Statistical Manual of Mental Disorders. However, no research has yet shown that complicated grief has incremental validity (i.e., predicts unique variance in functioning). The authors addressed this issue in 2 studies by comparing grief, depression, and posttraumatic stress disorder (PTSD) symptoms with different measures of functioning (interviewer ratings, friend ratings, self-report, and autonomic arousal). The 1st study (N = 73) used longitudinal data collected at 4 and 18 months postloss, and the 2nd study (N = 447) used cross-sectional data collected 2.5-3.5 years postloss. With depression and PTSD controlled, grief emerged as a unique predictor of functioning, both cross-sectionally and prospectively. The findings provide convergent support for the incremental validity of complicated grief as an independent marker of bereavement-related psychopathology.     

Teaching the Bible in the schools of the Labor and the Kibbutz Movements, 1921–1953

How the challenge of teaching the Bible was met by educators who were members of the Kibbutz and Labor movements during the years before the establishment of the Israeli State is the subject of the following essay. Years ago, Jacobus Schoneveld, (1976), recently followed by Asher Shkedi (2004) proposed dividing educators of the Labor and Kibbutz movements into three types: those who wished to stress “national reconstruction,” those directed toward teaching a “universal humanism” and those seeking to awaken “moral dialogue” and achieve “personal growth.” In fact, such clear-cut lines of demarcation did not exist. The goals were these, but approaches themselves were always mixed. One distinguishes educational goals better by a more simple division into the questions of what is to be taught (religious versus Secular materials) and through which ancillary disciplines. Doing so has the virtue of highlighting how these educators were animated by their quest after how best to teach Biblical morality with the aim of “shaping” the student or achieving “emulation,” especially by generating a “dialogue” between the pupil and the biblical text, leading to “personal growth.” These emphases tell us much about the pre-State educational mentality and pedagogical ideals.     

ABCs of principal–agent interactions: Accurate predictions,biased processes,and contrasts between working and delegating

We experimentally investigate people’s evaluations of incentive pay contracts and people’s predictions of others’ evaluations of incentive pay contracts. We emphasize that the construction of evaluations and predictions often includes two substeps, involving likelihood judgment and likelihood weighting. Predictors appear to be biased at both substeps but in opposing directions. Accurate overall predictions thus sometimes reflect two errors that are of the same magnitude and thereby offset. Moreover, predictions can become more inaccurate if one step is debiased but the other is left untouched. Importantly, principals deciding whether to delegate a task are susceptible to just one of the biases. Delegation assessments are thus often flawed, reflecting a single error that is not offset.     

Positivity ratio of flourishing individuals: Examining the moderation effects of methodological variations and chronological age

We tested the relationship between flourishing and positivity ratio while accounting for different measures of affect and rating scale formats. We further examined age-related differences in positivity ratio. Studies 1 and 2 showed that positivity ratio is affected by the measure used, but not by the rating scale format. Study 3 further showed that positivity ratio is higher among older adults. The above pattern of methodological variations was replicated in Study 4 with daily ratings of emotions and in Study 5 where emotions were rated on an extended scale. Study 5 also replicated the aforementioned age effect. Together these studies suggest that positivity ratio is moderated by methodological variants and individual differences, such as chronological age. Future studies should account for these possible moderation effects when exploring the positivity ratio and its relationship to flourishing.     

Money, Kisses, And Electric Shocks: On the Affective Psychology of Risk

Prospect theory's S-shaped weighting function is often said to reflect the psychophysics of chance. We propose an affective rather than psychophysical deconstruction of the weighting function resting on two assumptions. First, preferences depend on the affective reactions associated with potential outcomes of a risky choice. Second, even with monetary values controlled, some outcomes are relatively affect-rich and others relatively affect-poor. Although the psychophysical and affective approaches are complementary, the affective approach has one novel implication: Weighting functions will be more S-shaped for lotteries involving affect-rich than affect-poor outcomes. That is, people will be more sensitive to departures from impossibility and certainty but less sensitive to intermediate probability variations for affect-rich outcomes. We corroborated this prediction by observing probability-outcome interactions: An affect-poor prize was preferred over an affect-rich prize under certainty, but the direction of preference reversed under low probability. We suggest that the assumption of probability-outcome independence, adopted by both expected-utility and prospect theory, may hold across outcomes of different monetary values, but not different affective values.     

Mother-child patterns of coping with anticipatory medical stress

Maternal influences on children's fear and coping behaviors during a medical examination were studied in a pediatric outpatient clinic using the Dyadic Prestressor Interaction Scale (DPIS) to measure anticipatory reactions just prior to contact with the physician. Analysis of 50 mother-child dyads, including children from 4 to 10 years of age, revealed that the behaviors emitted by mother and child are likely to influence the child's ability to tolerate the medical experience. Maternal use of distraction and low rates of ignoring were associated with lower child distress and increased prosocial behaviors. Children's active exploration of the situation was more likely to occur when mothers provided their children with information, and was less likely when mothers reassured their children. Maternal reassurance of children and overt maternal agitation were associated with more maladaptive child responses. Age trends were also found in interactive patterns. Younger children were more likely to receive reassurance from mothers when they showed attachment. There was a stronger association between mother's information giving and child's exploring for children under 5 years, 9 months of age. Results supported the usefulness of the DPIS for investigation of child management techniques in this situation. Theoretical extension to attachment and stranger-approach situations was made. Suggestions for future studies to clarify the reciprocity of interactions or to determine causal direction between mother and child behaviors, as well as to evaluate the specificity or generality of these findings, were provided.     

Bruxism in children: Etiology and treatment

Bruxism is the nonfunctional clenching or grinding of the teeth. These behaviors are relatively common in children and adolescents. The psychologist and pediatrician need help in deciding whether or not this dysfunctional behavior is in need of treatment. The disorder can be defined as a multifaceted problem in which understanding the nature of the symptom (duration, intensity, damage) and the likely theoretical cause may determine the need for treatment. Many theories have not been well supported by comparative research. Hypothesized etiological factors for these behaviors include deviations from ideal occlusion, psychological stress, and various systemic or neurophysiological conditions. Interocclusal appliances, noctural alarms, and various psychological approaches appear to be efficacious in treating the disorder; however, decision making has been haphazard, often based on the clinician's theortical approach or the availability of devices rather than on a functional analyses of the individual's predisposing factors. Most effects of treatment, therefore, are short lived. Suggestions for future research are made to remedy these shortcomings and provide clinicians with assistance in treatment decisions.
