A picture is worth a thousand words: Children's representations of family as indicators of early attachment

To ascertain whether attachment representations at age 7 are related to early attachment behaviour, family drawings of 123 7-year-olds of known infant attachment status (25 avoidant, 80 secure, 18 resistant) were scored in four ways. Three of these were based in previous attachment research and one was based on a clinical method. The attachment-based coding schemes included specific markers for each attachment pattern (Kaplan & Main, 1985), global ratings (Fury, Carlson, & Sroufe, 1997) and efforts to classify each drawing as belonging to one of the three primary infant attachment groups (secure, avoidant, resistant). In the clinical scheme, children who had been resistant infants were distinguished from the others by use of overlapping and encapsulated figures. For the attachment based schemes, although individual markers were not successful in discriminating attachment groups, the more global approaches (aggregation of markers, global rating scales and judgments of attachment classification) succeeded in this task. In regression analyses controlling for concurrent child and parent measures, infant attachment did not make a significant contribution to predicting insecurity markers in drawings, although child current emotional functioning did. These findings linking attachment relationships with later representations of family relationships were in accord with the conception that avoidant attachment strategies de-emphasize intimate relationships, while resistant attachment strategies are preoccupied with close relationships. These links are most evident in global interpretive strategies rather than those that rely on specific markers.

Interpretation bias characterizes trait rumination

Background and objectives

Rumination, a maladaptive cognitive style of responding to negative mood, is thought to be maintained by a variety of cognitive biases. However, it is unknown whether rumination is characterized by interpretation biases.

Methods

Two experiments examined the link between rumination and interpretation biases, revealed in lexical-decision tasks (LDT). A homograph with both benign and ruminative or otherwise negative meaning was presented on each trial and followed by a letter string, to which participants responded by judging whether it was a word or a non-word. Letter strings were non-words or words related or unrelated to one meaning of the homograph.

Results

In both experiments, faster latencies to respond to targets related to the ruminative meaning of the homographs were produced by students with higher scores on self-report measures of rumination. Moreover, these biases were associated with both brooding, the maladaptive form of rumination, and reflection, the more adaptive component. No measure of rumination was significantly correlated with general biases toward negative meaning (Experiment 1) or with threatening interpretations of homographs (Experiment 2).

Limitations

The paucity of available rumination-related homographs dictated the use of non-fully randomized stimuli presentation (Experiment 1) or the use of only one set of the meanings associated with the homographs (Experiment 2).

Conclusions

Rumination is associated with a tendency to interpret ambiguous information in a rumination-consistent manner. This tendency may exacerbate ruminative thinking and can possibly be a target for future intervention.

Validating the Medical Data Interpretation Test in a Dutch population

Objective

To validate the Dutch translation of the Medical Data Interpretation Test.

Methods

A test–retest design with a 2-week interval was used.

Results

The intraclass correlation coefficient (ICC = .82), the limits-of-agreement interval (LOA = −8.96 to 2.48) and the test–retest reliability (Pearson's r = 86) suggest that the Dutch translation has good reproducibility. Construct validity was tested by two hypotheses, both of which were confirmed. University participants had higher test scores than non-university participants (p = .02), and males did not score differently than females (p = .61).

Conclusion

The results suggest that the Dutch version of the Medical Data Interpretation Test is an adequate scale to assess ability to interpret medical data.

Practice implications

Assessing patients’ numeracy skills before a counseling session will enable the counselor to adjust subsequent communication accordingly and, as such, improve the session's effectiveness.     

Multiparametric Magnetic Resonance Imaging for the Detection of Clinically Significant Prostate Cancer: What Urologists Need to Know. Part 2: Interpretation

BackgroundThere is large variability among radiologists in their detection of clinically significant (cs) prostate cancer (PCa) on multiparametric magnetic resonance imaging (mpMRI).ObjectiveTo reduce the interpretation variability and achieve optimal accuracy in assessing prostate mpMRI.Design, setting, and participantsHow the interpretation of mpMRI can be optimized is demonstrated here. Whereas part 1 of the “surgery-in-motion” paper focused on acquisition, this paper shows the correlation between (ab)normal prostate anatomical structures and image characteristics on mpMRI, and how standardized interpretation according to Prostate Imaging Reporting and Data System version 2 (PI-RADS v2) should be performed. This will be shown in individual patients.Surgical procedureTo detect csPCa, three mpMRI “components” are used: “anatomic” T2-weighted imaging, “cellular-density” diffusion-weighted imaging, and “vascularity” dynamic contrast-enhanced MRI.MeasurementsBased on PI-RADS v2, the accompanying video shows how mpMRI interpretation is performed. Finally, the role of mpMRI in detecting csPCa is briefly discussed and the main features of the recently introduced PI-RADS v2.1 are evaluated.Results and limitationsWith PI-RADS v2, it is possible to quantify normal and abnormal anatomical structures within the prostate based on its imaging features of the three mpMRI “components.” With this knowledge, a more objective evaluation of the presence of a csPCa can be performed. However, there still remains quite some space to reduce interobserver variability.ConclusionsFor understanding the interpretation of mpMRI according to PI-RADS v2, knowledge of the correlation between imaging and (ab)normal anatomical structures on the three mpMRI components is needed.Patient summaryThis second surgery-in-motion contribution shows what structures can be recognized on prostate magnetic resonance imaging (MRI). How a radiologist performs his reading according to the so-called Prostate Imaging Reporting and Data System criteria is shown here. The main features of these criteria are summarized, and the role of prostate MRI in detecting clinically significant prostate cancer is discussed briefly.     

Don’t panic: Interpretation bias is predictive of new onsets of panic disorder

Psychological models of panic disorder postulate that interpretation of ambiguous material as threatening is an important maintaining factor for the disorder. However, demonstrations of whether such a bias predicts onset of panic disorder are missing. In the present study, we used data from the Dresden Prediction Study, in which a epidemiologic sample of young German women was tested at two time points approximately 17 months apart, allowing the study of biased interpretation as a potential risk factor. At time point one, participants completed an Interpretation Questionnaire including two types of ambiguous scenarios: panic-related and general threat-related. Analyses revealed that a panic-related interpretation bias predicted onset of panic disorder, even after controlling for two established risk factors: anxiety sensitivity and fear of bodily sensations. This is the first prospective study demonstrating the incremental validity of interpretation bias as a predictor of panic disorder onset.     

Clinician accuracy when subjectively interpreting articulating paper markings

Aims:

The aim of this study was to determine whether Subjective Interpretation of paper markings is a reliable method for identifying the relative occlusal force content of tooth contacts.

Methodology:

295 clinicians selected the “Most Forceful” and “Least Forceful” occlusal contacts in six occlusal-view photographs of articulating paper marks that were later compared against computerized occlusal analysis relative occlusal force measurements of the same tooth contacts. Means and standard deviations were calculated by years in clinical practice and by number of occlusion courses taken. A Chi-square analysis was also performed.

Results:

The mean correct for 295 participant dentists was 1·53 (±1·234). There were no significant differences found for years in practice (P>0·16) or number of occlusion courses taken (P>0·75). The Chi-square analysis showed a sensitivity of 12·6%, a specificity of 12·4%, a positive predictive value of 12·58%, and a negative predictive value of 12·42%. Chance was calculated at 12·5% correct.

Conclusions:

Subjective Interpretation is an ineffective clinical method for determining the relative occlusal force content of tooth contacts. The reported low scores obtained from a large group of participant dentists suggest clinicians are unable to reliably differentiate high and low occlusal force from looking at articulating paper marks. This longstanding method of visually observing articulating paper marks for occlusal contact force content should be replaced with a measurement-based, objective method.
