Relationship Education for Military Couples: Recommendations for Best Practice

Military couples have a number of distinctive strengths and challenges that are likely to influence their relationship adjustment. Military couples' strengths include stable employment, financial security, and subsidized health and counseling services. At the same time, military couples often experience long periods of separation and associated difficulties with emotional disconnect, trauma symptoms, and reintegrating the family. This paper describes best practice recommendations for working with military couples, including: addressing the distinctive challenges of the military lifestyle, ensuring program delivery is seen as relevant by military couples, and providing relationship education in formats that enhance the accessibility of programs.     

Visual event-related potentials in schizotypal personality disorder and schizophrenia

Schizophrenia (SZ) occurs among a spectrum of disorders with similar characteristics, including schizotypal personality disorder (SPD). Visual processing disturbances have been reported in both disorders, but it is not yet clear which processes are disturbed in both SZ and SPD, suggestive of a common endophenotype, and which appear only in SZ. In order to address this question, the authors evaluated visual event-related potentials (ERPs) elicited during a line-orientation discrimination task in control, SPD, and SZ participants. Visual ERPs allow specification of both the time course and physiological correlates of visual perception and cognition. SZ patients had smaller P100 and P300a amplitudes and prolonged P300b latency compared to the control group. SZ patients also had smaller N160, N200, P300a, and P300b amplitudes compared to the SPD group. SPD participants did not differ from control participants on any ERP measure. These data documented pervasive abnormalities in visual perception and attention in SZ but not in SPD, suggesting that these visual ERP disturbances may not represent a common endophenotype.     

Emotional availability and psychosocial correlates among mothers in substance‐abuse treatment and their young infants

Emotional availability (EA) was investigated among low‐income mothers enrolled in substance‐abuse treatment and their young infants (n = 21) compared with a demographically matched group of mother–infant pairs who, by self‐report, were not at risk for substance abuse (n = 27). The mother–infant dyads in the treatment group generally demonstrated poorer EA functioning than those in the comparison group, but few differences between the groups on individual dimensions of EA were significant. This finding was notable considering that mothers in treatment reported significantly higher levels of depressive symptoms and psychological stress. Treatment effects may have buffered the negative impact of depression and psychological stress on mothers' EA scores. The clinical implications of the findings are discussed as they relate to substance‐abuse‐treatment services for pregnant and parenting women.     

Do Geographic Regions with Higher Suicide Rates also have Higher Rates of Nonfatal Intentional Self‐Harm?

Fatal and nonfatal intentional self‐harm events in eight U.S. states were compared using emergency department, hospital, and vital statistics data. Nonfatal event rates increased by an estimated 24.20% over 6 years. Case fatality ratios varied widely, but two northeastern states' total event rates (fatal plus nonfatal) were very high (New Hampshire 206.5/100,000 person years; Massachusetts 166.7/100,000). Geographic context did not uniformly impact the likelihood of self‐harm across event types. The state‐level public health burden posed by such acts cannot, therefore, be accurately estimated from either mortality or morbidity data alone.     

The occurrence of an increase in correlation with explicit selection

It is generally believed that correlations and standard deviations measured within an explicitly selected group must be smaller than those within an applicant population. A small data set is used to show that this is not always true, and that both validity and reliability estimates within a selected group can exceed those within the applicant population. The increase in correlation within the explicitly selected group is tied to an increase in standard deviation of the predictor in the selected group. This conclusion extends Levin's (1972) result for the case of incidental selection, selection on an unmeasured third variable. If possible, theoretical derivations should not be limited to the case where the predictor standard deviation in the applicant population exceeds that in the selected group. When such a situation occurs in observed data, it cannot be immediately dismissed as an artifact.The author would like to thank Mark L. Davison and other reviewers for their comments on earlier drafts of the paper. An anonymous reviewer provided a better example than the original one, resulting in a more general conclusion.This work was supported in part by a Dissertation Fellowship from the University of Minnesota.     

Naming reaction times to tachistoscopically presented pictures: some evidence of right hemisphere encoding

The present study measured naming reaction times by normal subjects to unilaterally presented picture stimuli. Significant differences in picture-naming reaction time did not exist between left and right visual-field stimulations. The right hemisphere in the intact brain is capable of generating a verbal label for pictured stimuli. A psychological model suggests that a possible processing synergy between the two hemispheres may be tied to spatial processing and elementary linguistics.
