Psychometric properties of the mutuality scale in Swedish dyads with Parkinson's disease

Sexual Fantasies and Harmful Sexual Interests: Exploring Differences in Sexual Memory Intensity and Sexual Fantasy Characteristics

The perpetration of harmful sexual behavior is a global concern, with deviant sexual fantasies identified as a prominent etiological risk factor. However, the concepts of state sexual fantasy characteristics (e.g., vividness and emotionality) and associated trait sexual memory intensity have received minimal investigation concerning harmful sexual interests, formulating the impetus for this research. Two online surveys were conducted in community populations. Study 1 (N = 414) aimed to validate the psychometric properties of a trait sexual memory intensity scale (SMIS) through principal components analysis, confirmatory factor analysis, and evaluation of concurrent validity. Study 2 (N = 820) endeavored to explore associations between state sexual fantasy characteristics and cognitive-behavior variables (e.g., frequency of masturbation to a reported fantasy), and evaluate differences in fantasy characteristics and SMIS scores between participants with and without harmful sexual interests. Collectively, results supported the factor structure, concurrent validity, and internal consistency of the SMIS, while revealing significant associations between the SMIS, sexual fantasy characteristics, and several variables. Significant differences in sexual fantasy characteristics and SMIS scores were evident but variable among harmful sexual interests. Findings encourage the consideration and research of interventions focused on impairing mental imagery and memory in the management of harmful sexual interests.

Development and validation of two versions of the Nurse-Patient Mutuality in Chronic Illness scale

AIMS

The aim of the study was to develop and psychometrically test the Nurse-Patient Mutuality in Chronic Illness (NPM-CI) scale in two versions, one for nurses and one for patients.

METHOD

A multiphase methodological study was conducted. In the first phase, a qualitative investigation was conducted through interviews and an analysis of the content; inductively, the items of two instruments were generated, one for nurses and one for patients. In the second phase, the content and face validity were assessed through the expert consensus method. In the third phase, exploratory factor analysis (EFA), Cronbach's alpha test, intraclass correlation and Pearson correlation coefficients were conducted to estimate construct, criterion validity and instrument reliability. For each phase, the sample included nurses and patients recruited from a large hospital in Northern Italy. Data collection was conducted between June and September 2021.

RESULTS

Nurse and patient versions of the NPM-CI scale were developed. Two rounds of consensus reduced the items from 39 to 20; content validity index ranged between 0.78 and 1, content validity ratio was 0.94. Face validity indicated clarity and comprehensibility of the items. EFA identified three latent factors for both the scales. Internal consistency was satisfactory, with Cronbach's alphas ranging between .80 and .90. Test-retest stability was suggested, with an intraclass correlation coefficient of .96 (nurse scale) and .97 (patient scale). Predictive validity was established, with a Pearson correlation coefficient of .43 (nurse scale) and 0.55 (patient scale) between the mutuality scales and satisfaction in providing and receiving care.

CONCLUSION

The results suggest that the NPM-CI scales are sufficiently valid and reliable for the clinical practice among chronic illness patients and the nurses caring for them. A more in-depth exploration of this construct in the context of nursing and patient outcomes is warranted.

PATIENT OR PUBLIC CONTRIBUTION

Patients were involved in all study phases.

IMPACT

Mutuality is fundamental in the relationship between nurse and patient, based on trust, equality, reciprocity, and mutual respect. The NPM-CI scale was developed and psychometric estimated through a multiphase study in both nurse and patient versions. The NPM-CI scale measures the factors of 'developing and going beyond', 'being the point of reference' and 'deciding and sharing care'. The NPM-CI scale allows us to measure mutuality in clinical practice and research. Expected outcomes and influencing factors for patients and nurses could be associated.

Pharmacotherapy for Obstructive Sleep Apnoea and Coupled Life: A Descriptive Phenomenological Study of a Complex Interaction

BACKGROUND

Obstructive Sleep Apnoea (OSA) is a common chronic sleep-related breathing disorder. Drug therapy is a recent approach to treating OSA, and no data is available regarding its effects on a couple's life. The aim of this study was to investigate the impact on couples' lives of a novel drug treatment for OSA.

METHODS

Participants of a trial on new drug therapy (reboxetine plus oxybutynin) for OSA were interviewed. The study was conducted using a descriptive phenomenological approach by Sundler et al. Results: Ten patients and six of their partners were recruited through a purposive sampling between February and April 2021. The results indicate that drug treatment of OSA had a favourable impact on the couples' lives. Pharmacotherapy improved self-reported sleep quality, as the absence of CPAP allows people to sleep closer to the bed partner and because the patient does not have to sleep in a forced position. Moreover, the couples developed teamwork from the beginning which appeared to be crucial during the trial, especially when some difficulties and adverse events occurred.

CONCLUSIONS

This study presents the presence of a positive closed loop that could be considered a predictor of adherence to drug therapy.

Exploring Factors Associated With Family Caregivers' Preparedness to Care for an Older Family Member Together With Home Care Nurses: An Analysis in a Swiss Urban Area

Introduction:

Home-dwelling older people with chronic diseases often need the support of informal and formal caregivers in order to continue living at home. Family members, however, need to be willing and prepared for caregiving together with home care nurses.

Objectives:

The purpose of this study was to explore factors associated with family caregivers’ preparedness to care for older home-dwelling adults who also receive home care nursing services.

Methods:

For this cross-sectional correlational study, a structured questionnaire was sent to family caregivers of adults aged 65 years or older receiving services from a community care agency. A total of 243 participants returned the questionnaire, of which 199 could be analyzed.

Results:

The stepwise backward regression model explained 29.1% of the variance of family caregivers’ preparedness. Mutuality was the most strongly associated factor with family caregivers’ preparedness whereas professional involvement of family caregiver in care process was important as well. Care intensity showed no significant impact.

Conclusion:

Nurses should support the whole family emotionally, and appreciate, admire, reinforce, and respect the caregivers’ situation. Home care nurses need to invest in helping families to find solutions, to strengthen their relationships between family members and the older person dwelling at home.

Independent and combined associations of urinary heavy metals exposure and serum sex hormones among adults in NHANES 2013-2016

Accumulating evidences indicated that heavy metals may disrupt human sex hormones. However, the combined effects of heavy metals on sex hormones remain to be clarified. To explore the independent and combined associations between heavy metal exposure and serum sex hormones among adults, data of 2728 adults from the National Health and Nutrition Examination Survey (NHANES) was applied. We examined independent and combined associations of fourteen urinary heavy metals and three serum sex steroid hormones (total testosterone (TT), estradiol (E2) and sex hormone-binding globulin (SHBG)). Multivariate linear regression was used to evaluate the independent associations between metal exposure and sex hormone alterations. Principle component analysis -weighted quantile sum regression (PCA-WQSR) model was performed to estimate the combined associations in our individuals. In the co-exposure model, we determined that weighted quantile sum (WQS) index of industrial pollutants was negatively associated with E2 in females (WQS Percent change_8-metal = -20.6%; 95% CI: -30.1%, -9.96%), while in males WQS index of water pollutants was negatively related to SHBG (WQS Percent change_8-metal = -5.35%; 95% CI: -9.88%, -0.598%). Cadmium (Cd), tin (Sn) and lead (Pb) were the dominating metals of female E2-negative association while Ba was the leading contributor related to male SHBG reduction, which was consistent with the results of multivariate linear regression. Additionally, in postmenopausal women, the associations of E2 decrease with heavy metal co-exposure remained significant while Cd and monomethylarsonic acid (MMA) were identified as hazardous metals in the mixture. We concluded that the exposure to heavy metals was associated with human sex hormone alterations in independent or combined manners. Considering the design of NHANES study, further studies from other national-representative surveys are necessary.

Self-Report and Caregiver Proxy-Report Agreement of Perceived Chronic Stress and Mutuality in Poststroke Aphasia

Background People with aphasia (PWA) report higher levels of stress in comparison to stroke survivors without aphasia. If untreated, chronic stress is known to have detrimental effects to the body and brain and can negatively impact health and well-being. According to extant literature, self- and proxy-report agreement on objective domains is higher than on subjective domains, like chronic stress. In addition, high levels of mutuality, also known as shared feelings between two people, have been strongly associated with low levels of stress in stroke survivors. Little is known, however, of the agreement between self-report and caregiver proxy-report on perceived chronic stress or mutuality in PWA. Purpose The proposed study sought to examine (a) the degree of agreement between caregiver proxy-report and PWA self-report on perceived stress and (b) the relationship between perceived stress and mutuality between PWA and their caregivers. Method The Modified Perceived Stress Scale and the Mutuality Scale were administered to 21 PWA/caregiver dyads. An independent-samples t test was conducted to determine if there were significant differences in perceived stress and mutuality as reported by PWA, their caregiver, and their caregiver's proxy-report. A Pearson correlation was performed to determine the level of agreement across questionnaires. Results There was a moderate correlation between the proxy-report and self-report for perceived stress. On average, proxy-reports for perceived stress were significantly higher than PWA self-reports. Overall, mutuality was high among the dyads. There was moderate agreement between caregiver's mutuality and proxy-report agreement on perceived stress. Lastly, our findings do not indicate that caregiver's perceived stress influenced their perception of the PWA's perceived stress. Conclusion The results of this study provide support for the use of proxy-derived information in perceived stress with the use of a mutuality scale.

Mediating effect of mutuality on caregiver burden in Parkinson's disease partners

Objectives: Parkinson's disease (PD) is a complex neurodegenerative disorder with a broad list of motor and non-motor symptoms (NMS) that has been shown to affect the relationship quality (mutuality) and caregiver burden. However, little is known if the effect of motor and NMS on caregiver burden is mediated by mutuality. Therefore, the aim of this study was to explore if perceived mutuality by patients and partners mediates the effect of motor and NMS on caregiver burden.Methods: Data were collected from 51 dyads with one PD patient, including measures of motor signs, NMS, impaired cognition, patients' and partners' perceived mutuality, caregiver burden and dependency in activities in daily life (ADL). Structural equation model with manifest variables were applied to explore if patients' and partners' mutuality score mediated the effect of motor signs, NMS, ADL or impaired cognition on caregiver burden.Result: Our results suggest that having a partner with PD who is dependent in ADL or has impaired cognition decreases partners' mutuality which leads to elevated burden. Motor symptoms or other NMS were not associated with partners' mutuality or caregiver burden. Instead, increasing severity of motor symptoms decrease patients' mutuality in turn leading to lower level of partners' mutuality.Conclusion: Our findings enhance the understanding of the complexity of living with PD for the partner and suggest that clinical assessment should include evaluation of how PD symptoms influence the quality of the relationship between partners and patients.

Mediating Effect of Mutuality on Health-Related Quality of Life in Patients with Parkinson's Disease

The relationship quality, mutuality, has been identified as a protective factor in family care situations, but its role in mediating health-related quality of life (HRQoL) in patients having Parkinson's disease (PD) is not known. Data on patients' and partners' mutuality (MS), motor signs (UPDRS III), non-motor symptoms (NMSQuest), impaired cognition (IQCODE), dependency in activities of daily life (ADL), and HRQoL (PDQ8) were collected from 51 dyads. Structural equation model with manifest variables was applied to explore if the MS score mediated the effect of UPDRS III, NMSQuest, IQCODE, and dependency in ADL on PDQ8. The results suggest that increasing severity of motor and non-motor symptoms decreases patients' mutuality which leads to worse HRQoL. Partners' mutuality mediated the effect of impaired cognition which in turn decreased patients' mutuality. The findings enhance our understanding of how various symptoms may influence PD patients' HRQoL. This may help clinicians to personalize interventions to provide more effective interventions to improve the lives of patients with PD.

Determinants of Dyadic Relationship and Its Psychosocial Impact in Patients with Parkinson's Disease and Their Spouses

The caregiver-care receiver relationship (mutuality) in Parkinson's disease (PD) and its association with motor and non-motors symptoms, health-related quality of life (HRQoL), and caregiver burden have not fully been investigated. The aim of our study was to explore if (1) the level of mutuality perceived by PD-patients and PD-partners differs, (2) different factors are associated with perceived mutuality by PD-patients and PD-partners, and (3) mutuality is associated with PD-patients health-related quality of life (HRQoL) and caregiver burden. We collected data on motor signs (UPDRS III), non-motor manifestations (NMSQuest), PD-patients' cognition (IQCODE), mutuality scale (MS), PD-patients' HRQoL (PDQ8), and caregiver burden (CB) from 51 PD dyads. Predictors were identified using multivariate regression analyses. Overall, the dyads rated their own mutuality as high with no significant difference between the dyads except for the dimension of reciprocity. PD-patients' MS score (p = .001) and NMSQuest (p ≤ .001) were significant predictors of PDQ8. Strongest predictor of CB was PD-partners' MS score (<.001) and IQCODE (p = .050). In general, it seems that non-motor symptoms contribute to a larger extent to the mutual relationship in PD-affected dyads than motor disabilities.
