Background. Previous studies have suggested changes in self-concept with successful treatment of primary nocturnal enuresis (PNE), but behavioral changes have not been reported as a consistent associated finding. Objective. To determine if self-concept and behavior change after 6 months of treatment of monosymptomatic PNE by conditioning alarm or desmopressin acetate (DDAVP). Design. Randomized, controlled trial in an inner-city hospital clinic. Subjects were 182 children referred or recruited through media publicity, randomly assigned both to 1 of 8 pediatricians and 1 of 3 treatment groups (alarm, DDAVP, or placebo). Included were children >7 years old with PNE, no daytime symptoms, bladder capacity >50% expected, and wetting >3 times a week. Excluded were children with central nervous system disorders or developmental delays, and those currently on DDAVP or alarm. Subjects completed thePiers-Harris Children's Self-Concept Scale and Harter's Perceived Competence Scale for Children (PCSC) at initial visit and after 6 months of treatment. Parents completed the Achenbach Child Behavior Checklist (CBCL) at the same times. Results. After 6 months of treatment the Piers-Harris total score showed a highly significant treatment by period interaction effect for DDAVP, a significant effect for alarm, and no effect for placebo. For children who achieved 75% dryness the CBCL showed a treatment by improvement interaction effect that was highly significant for DDAVP and placebo with no effect for alarm. For the PCSC there were no treatment or outcome interaction effects. After 6 months of treatment there were significant changes over time unrelated to outcome or treatment in the Piers-Harris Subscales and in the CBCL Internalizing and Externalizing Scores, and the Social Thought and Attention Problems Subscales. The PCSC was more stable with no changes in total score, and positive changes over time in only 2 Subscales, Scholastic and Social. Conclusion. Children's self-concept improved with the type of treatment and amount of success. Parents' perceptions of behavior improve with type of treatment and amount of success. Children rate their self-concept and some physical attributes better after treatment with any of DDAVP, alarm, or placebo regardless of outcome. Frequent follow-up with emotional support and encouragement appear to be important components of an efficacious intervention for children with nocturnal enuresis.

Past research in the literature on the self has addressed how self-concept clarity changes over time. In this study, we use a cross-sectional research design to examine the relationship between self-perceptions of identity change and self-concept clarity, showing how fluctuations in self-concept clarity relate to two discrete dimensions of perceived identity change: the magnitude and direction of change. A survey was administered to 854 study participants that measured perceived changes in 12 discrete identities (four person, four role, and four social identities) over a 6-month period. The results reveal that generally the more severe one's perceived experience of identity change, the lower their degree of self-concept clarity. However, when the direction of one's perceived identity change is progressive (i.e., developing into an identity) rather than regressive (i.e., exiting out of an identity), one's degree of self-concept clarity increases.

Abstract. Summary: Background: We aimed at estimating the agreement between the Medicap® (photo-optical) and Radiometer® (electro-chemical) sensors during exercise transcutaneous oxygen pressure (tcpO2) tests. Our hypothesis was that although absolute starting values (tcpO2rest: mean over 2 minutes) might be different, tcpO2-changes over time and the minimal value of the decrease from rest of oxygen pressure (DROPmin) results at exercise shall be concordant between the two systems. Patients and methods: Forty seven patients with arterial claudication (65 + / - 7 years) performed a treadmill test with 5 probes each of the electro-chemical and photo-optical devices simultaneously, one of each system on the chest, on each buttock and on each calf. Results: Seventeen Medicap® probes disconnected during the tests. tcpO2rest and DROPmin values were higher with Medicap® than with Radiometer®, by 13.7 + / - 17.1 mm Hg and 3.4 + / - 11.7 mm Hg, respectively. Despite the differences in absolute starting values, changes over time were similar between the two systems. The concordance between the two systems was approximately 70 % for classification of test results from DROPmin. Conclusions: Photo-optical sensors are promising alternatives to electro-chemical sensors for exercise oximetry, provided that miniaturisation and weight reduction of the new sensors are possible.
