Abstract Online self-reported 24-h dietary recall systems promise increased feasibility of dietary assessment. Comparison against interviewer-led recalls established their convergent validity; however, reliability and criterion-validity information is lacking. The validity of energy intakes (EI) reported using Intake24, an online 24-h recall system, was assessed against concurrent measurement of total energy expenditure (TEE) using doubly labelled water in ninety-eight UK adults (40–65 years). Accuracy and precision of EI were assessed using correlation and Bland–Altman analysis. Test–retest reliability of energy and nutrient intakes was assessed using data from three further UK studies where participants (11–88 years) completed Intake24 at least four times; reliability was assessed using intra-class correlations (ICC). Compared with TEE, participants under-reported EI by 25 % (95 % limits of agreement −73 % to +68 %) in the first recall, 22 % (−61 % to +41 %) for average of first two, and 25 % (−60 % to +28 %) for first three recalls. Correlations between EI and TEE were 0·31 (first), 0·47 (first two) and 0·39 (first three recalls), respectively. ICC for a single recall was 0·35 for EI and ranged from 0·31 for Fe to 0·43 for non-milk extrinsic sugars (NMES). Considering pairs of recalls (first two v. third and fourth recalls), ICC was 0·52 for EI and ranged from 0·37 for fat to 0·63 for NMES. EI reported with Intake24 was moderately correlated with objectively measured TEE and underestimated on average to the same extent as seen with interviewer-led 24-h recalls and estimated weight food diaries. Online 24-h recall systems may offer low-cost, low-burden alternatives for collecting dietary information.

The present study assessed the rate of depressive personality (DP), as measured by the self-report instrument depressive personality disorder inventory (DPDI), among 159 clients entering psychotherapy at an outpatient university clinic. The presenting clinical profile was evaluated for those with and without DP, including levels of depressed mood, other psychological symptoms, and global severity of psychopathology. Clients were followed naturalistically over the course of therapy, up to 40 weeks, and reassessed on these variables again after treatment. Results indicated that 44 percent of the sample qualified for DP prior to treatment, and these individuals had a comparatively more severe and complex presenting disposition than those without DP. Mixed-model repeated-measures analysis of variance was used to examine between-groups changes on mood and global severity over time, with those with DP demonstrating larger reductions on both outcome variables, although still showing more symptoms after treatment, than those without DP. Only eleven percent of the sample continued to endorse DP following treatment. These findings suggest that in routine clinical situations, psychotherapy may benefit individuals with DP.

Pilot Feasibility Study

Purpose: This study explored the relationship between migrant farmworker (MFW) stress and salivary cortisol (sC) in a sample of MFWs prior to migration. Sample: The sample, 40 ( N = 14 male, 26 female) adult MFWs residing in the lower Rio Grande Valley of Texas, primarily comprised middle-aged immigrants with a middle-school education. Design: This pilot feasibility study included a self-report farmworker stress inventory and five serial sC specimens in 24 hr. Results: The sC measures reflected an expected diurnal pattern. Lower total cortisol (area under the curve with respect to ground) was significantly associated with greater waist circumference ( r = –.63, p ≤ .01). Repeated measures analysis of variance (ANOVA) indicated that participants who perceived high levels of farmworker stress exhibited a significant change in sC over time; F(2.14, 72.65) = 43.90, p < .001. High- and low-perceived-stress groups differed significantly in the trajectory of changes in sC over the five time points. Conclusion: MFWs experienced significant levels of stress during premigration. Their sC responses varied significantly by level of perceived farmworker stress. Lower perceived stress may reflect blunting of the sC response pattern.

Main Effect

There may be differential benefits from regular exercise for elderly persons, and their rationales about exercise can influence the likelihood that they will do it 98 elderly persons (29 men, M age = 66.3 yr., SD = 9.1, Range = 51–90 and 69 women, M age = 72.7 yr., SD = 10.3, Range = 53–94) were given two self-report surveys of 13 items each consisting of statements about jogging, not jogging, or engaging in other forms of exercise. Only one man and one woman completed the “reasons for jogging” form, while 96 elderly persons completed the “reasons for not jogging” form. A two-way (repeated-measures) analysis of variance indicated a significant main effect for differences among 10 items dealing with “reasons for not jogging.” These reasons included engaging in another form of aerobic activity (such as walking), having a health condition that prevented jogging, and jogging as too uncomfortable.

Purpose This retrospective study used a cochlear implant registry to determine how performing speech recognition candidacy testing in quiet versus noise influenced patient selection, speech recognition, and self-report outcomes. Method Database queries identified 1,611 cochlear implant recipients who were divided into three implant candidacy qualifying groups based on preoperative speech perception scores (≤ 40% correct) on the AzBio sentence test: quiet qualifying group, +10 dB SNR qualifying group, and +5 dB SNR qualifying group. These groups were evaluated for demographic and preoperative hearing characteristics. Repeated-measures analysis of variance was used to compare pre- and postoperative performance on the AzBio in quiet and noise with qualifying group as a between-subjects factor. For a subset of recipients, pre- to postoperative changes on the Speech, Spatial and Qualities of Hearing Scale were also evaluated. Results Of the 1,611 patients identified as cochlear implant candidates, 63% of recipients qualified in quiet, 10% qualified in a +10 dB SNR, and 27% qualified in a +5 dB SNR. Postoperative speech perception scores in quiet and noise significantly improved for all qualifying groups. Across qualifying groups, the greatest speech perception improvements were observed when tested in the same qualifying listening condition. For a subset of patients, the total Speech, Spatial and Qualities of Hearing Scale ratings improved significantly as well. Conclusion Patients who qualified for cochlear implantation in quiet or background noise test conditions showed significant improvement in speech perception and quality of life scores, especially when the qualifying noise condition was used to track performance.

Preliminary research has suggested that wearable cameras may reduce under-reporting of energy intake (EI) in self-reported dietary assessment. The aim of the present study was to test the validity of a wearable camera-assisted 24 h dietary recall against the doubly labelled water (DLW) technique. Total energy expenditure (TEE) was assessed over 15 d using the DLW protocol among forty adults (n 20 males, age 35 (sd 17) years, BMI 27 (sd 4) kg/m2 and n 20 females, age 28 (sd 7) years, BMI 22 (sd 2) kg/m2). EI was assessed using three multiple-pass 24 h dietary recalls (MP24) on days 2–4, 8–10 and 13–15. On the days before each nutrition assessment, participants wore an automated wearable camera (SenseCam (SC)) in free-living conditions. The wearable camera images were viewed by the participants following the completion of the dietary recall, and their changes in self-reported intakes were recorded (MP24+SC). TEE and EI assessed by the MP24 and MP24+SC methods were compared. Among men, the MP24 and MP24+SC measures underestimated TEE by 17 and 9 %, respectively (P< 0·001 and P= 0·02). Among women, these measures underestimated TEE by 13 and 7 %, respectively (P< 0·001 and P= 0·004). The assistance of the wearable camera (MP24+SC) reduced the magnitude of under-reporting by 8 % for men and 6 % for women compared with the MP24 alone (P< 0·001 and P< 0·001). The increase in EI was predominantly from the addition of 265 unreported foods (often snacks) as revealed by the participants during the image review. Wearable cameras enhance the accuracy of self-report by providing passive and objective information regarding dietary intake. High-definition image sensors and increased imaging frequency may improve the accuracy further.

This study evaluated the psychometric properties of a self-report scale for assessing perceived driver competence, labeled the Self-Efficacy Scale for Driver Competence (SSDC), using item response theory analyses. Two samples of Swedish driving-license examinees (n = 795; n = 714) completed two versions of the SSDC that were parallel in content. Prior work, using classical test theory analyses, has provided support for the validity and reliability of scores from the SSDC. This study investigated the measurement precision, item hierarchy, and differential functioning for males and females of the items in the SSDC as well as how the rating scale functions. The results confirmed the previous findings; that the SSDC demonstrates sound psychometric properties. In addition, the findings showed that measurement precision could be increased by adding items that tap higher self-efficacy levels. Moreover, the rating scale can be improved by reducing the number of categories or by providing each category with a label.

Dukungan agar ibu menyusui bayi merupakan hal penting dalam menginisiasi dan mempertahankan pemberian ASI. Strategi dibutuhkan untuk mendukung keberhasilan menyusui. Tujuan penelitian adalah menganalisis efektivitas comprehensive breastfeeding education terhadap keberhasilan pemberian (ASI) pada periode postpartum. Jenis penelitian ini menggunakan kuasi eksperimen one group pre post test repeated measured design. Jumlah sampel sebanyak 22 ibu dengan menggunakan teknik accidental sampling. Pengumpulan data dilaksanakan pada bulan September–Oktober 2013 di Puskesmas wilayah Kota Tangerang Selatan. Intervensi dilakukan selama 30 menit. Pengumpulan data dilakukan sebelum intervensi, 3 hari setelah intervensi (post1), dan 10 hari setelah intervensi (post 2). Pengumpulan data menggunakan kuesioner dan observasi. Keberhasilan pemberian ASI berdasar pada parameter pengetahuan, langkah menyusui, perlekatan bayi, dan kecukupan ASI. Analisis data menggunakan general linear model repeated measureANOVA. Hasil penelitian menunjukkan adanya signifikansi comprehensive breastfeeding education (p=0.001). Rata-rata keberhasilan pemberian ASI sebelum dan setelah intervensi meningkat. Sebesar 93,9% intervensi memengaruhi tingkat keberhasilan. Rata-rata sebelum intervensi 56,74 (SD 5,92), post 1 sebesar 60,83 (SD 6,38) dan post2 sebesar 74,55 (SD 5,32). Subvariabel yang memiliki efek secara signifikan setelah intervensi adalah pengetahuan (p=0.001) dan langkah menyusui (p=0.001), sedangkan subvariabel perlekatan bayi (p=0.061) dan kecukupan ASI (p=0.162) tidak secara signifikan berbeda antara sebelum dan setelah intervensi. Pelaksanaanbreastfeeding education disarankan pada ibu agar dapat melakukan posisi perlekatan bayi yang benar sehingga dapat mengurangi masalah-masalah berkaitan dengan perlekatan yang tidak sesuai seperti puting perih, lecet atau berdarah, dan bayi kurang puas dalam menyusu yang bisa mengakibatkan gagalnya program ASI ekslusif.Kata kunci:Menyusui, pendidikan, perlekatan, postpartum AbstractBreastfeeding have still been problem for adequate newborn nutrition. Adequate breastfeeding support is essential for mothers to initiate and maintain optimal breastfeeding practices. A strategic needed to support successful breastfeeding. The purpose of research is to analyze the effectiveness comprehensive breastfeeding education on successful breastfeeding at postpartum periods. A quasi-experimental one group pretest, post test, repeated mesaured was used. This study was conducted at public health in Tangerang Selatan municipality in September–October 2013 among 22 postpartum mothers, convenience sampling methods. Intervention was done 30 minute. Data were collected before intervention (pretest), third day after intervention (post 1) and tenth day after intervention (repeated/post 2) using four parameter, that are knowledge, breastfeeding steps, proper lacth-on and adequate breastmilk. Using repeated measures analysis of variance there was a significant increase (p=0.001) in the overall Successful breastfeeding mean. Around 93,9% the effectiveness of intervention influence on successful. The mean before intervention is 56,74 (SD 5,92), increased at post 1:60,83 (SD 6,38) and post 2:74,55 (SD 5,32). Subvariable which has effect significantly after intervention is knowledge (p=0.001) and breastfeeding steps (p=0.001), in contrary, proper latch-on (p=0,061) and adequate breastmilk (p=0.162) have no significant effect after intervention. Suggestion to support breastfeeding education and counselling proper latch-on adequately that can decrease the problem such as painful, creaks or bloody putting.Key words: Breastfeeding, education, latch-on, postpartum

The purpose of this longitudinal, descriptive study was to observe changes in maximal strength measured via isometric clean grip mid-thigh pull and home runs (total and home runs per game) across three years of training and three competitive seasons for four National Collegiate Athletic Association (NCAA) Division 1 baseball players. A one-way repeated measures analysis of variance (ANOVA) was performed, revealing significant univariate effects of time for peak force (PF) (p = 0.003) and peak force allometrically scaled (PFa) (p = 0.002). Increases in PF were noted from season 1 to season 2 (p = 0.031) and season 3 (p = 0.004), but season 2 was not significantly different than season 3 (p = 0.232). Additionally, increases in PFa were noted from season 1 to season 2 (p = 0.010) and season 3 (p < 0.001), but season 2 was not significantly different than season 3 (p = 0.052). Home runs per game rose from the 2009 (0.32) to 2010 season (1.35) and dropped during the 2011 season (1.07). A unique aspect of the study involves 2010 being the season in which ball-bat coefficient of restitution (BBCOR) bats were introduced to the NCAA competition.

The response of fish communities and stream habitat to four riparian harvest treatments was studied in north-central Minnesota to determine if riparian harvest with two different harvest systems degrades stream systems. Treatments included control (no harvest), riparian control, cut-to-length riparian thin, and tree length riparian thin. Fish and habitat data were collected from 50 m reaches above, within, and downstream of each treatment 1 year preharvest (1997) and 3 years postharvest (1998–2000). Repeated measures analysis revealed few effects due to treatment; however, there was a 6%–10% significant reduction in canopy cover. Percent fine sediments increased significantly (15%) system-wide following forest harvest and persisted through 2000. This increase in fine sediments was correlated with a decrease in fish biotic integrity (r = –0.31). Habitat and fish variables were influenced more by year-to-year variation than by harvest treatment, suggesting that factors operating at a broader basin-wide scale may influence fish and habitat or mask any site-level harvest effects in this low-gradient stream system. Residual riparian basal areas ≥12.3m2/ha along reaches ≤200 m in length may be adequate to protect fish and habitat in these low-gradient streams, but basin-wide effects of harvest deserve more scrutiny.
