The mediating effect of after-midnight use of digital media devices on the association of internet-related addictive behavior and insomnia in adolescents.

Background: There is evidence that overexposure to digital media devices (DMD) can not only lead to addictive patterns of internet use, but also cause insomnia symptoms. The aim of this cross-sectional study among adolescents is to provide an estimate of the prevalence of sleep impairments and to explore the mediating role of after-midnight use of DMD between internet-related addictive behavior (IRAB) and insomnia. Methods: 2,712 school students from Styrian schools participated in a population-representative online survey in a supervised school setting in spring 2022. School students were screened using established and validated scales. Data analysis was carried out using multiple imputation, linear multilevel regression and mediation analysis. Results: Prevalence estimation indicates high proportions of clinically relevant moderate [12.6% (11.3%; 14.1%)] and severe [3.6% (2.9%; 4.4%)] insomnia, with an additional 30.6% (29.0%; 32.2%) at subthreshold level. DMD are typically used after midnight an average of 1.66 (1.58; 1.75) evenings with subsequent school day per school week. Linear multilevel regression analysis shows significant associations for sleep disparities as outcome variable e.g., with generalized anxiety [b = 0.329 (0.287; 0.371)], after-midnight use of DMD [b = 0.470 (0.369; 0.572)] and IRAB [b = 0.131 (0.097; 0.165)]. Mediation analysis shows a mediated proportion of 18.2% (13.0%; 25.0%) of the association of IRAB and insomnia by after-midnight use of DMD [Indirect effect: b = 0.032 (0.023; 0.040), direct effect: b = 0.127 (0.083; 0.170)]. Conclusions: Although the cross-sectional nature of this study limits causal inference, the results indicate a need for policies, which are already in preparation in Styria as part of a respective action plan.

Toxicity and quality of life outcomes in ovarian cancer patients participating in randomized controlled trials.

MAIN PURPOSE: The objective of this study was to determine the relationship between clinician-graded symptoms based on the common toxicity criteria (CTC) and patient-reported quality of life (QoL). We hypothesized that toxicity symptoms that are objective or observable would have a higher correlation with QoL than subjective data. MATERIAL AND METHODS: A retrospective analyses of data from three closed randomized chemotherapy trials was performed. A total of 2,110 patients with ovarian cancer (stage IIB-IV) who had complete toxicity and QoL data at cycles 3 and 6 were included. Toxicities were graded according to the National Cancer Institute Common Toxicity Criteria. Quality of life was assessed every other cycle by using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30). MAIN RESULTS: Correlations between CTC grading and the QLQ-C30 functioning scales were weak (<0.30); correlation coefficients between CTC ratings and the QLQ-C30 symptom scales including nausea, vomiting, constipation, pain, and dyspnea ranged from 0.32 to 0.49 except for constipation (0.55). On a symptom level exact agreement between clinician and patient reporting ranged from 54.2% (pain) to 80.8% (emesis/vomiting). When symptom grading differed, patients reported greater severity for pain, constipation, and dyspnea, whereas clinicians graded emesis/vomiting and nausea as more severe than the grading by patients. CONCLUSION: Patient experience is not routinely captured by CTC toxicity scales. Therefore, clinicians should not entirely rely on the CTC grading but consider patient-reported outcomes as well.

Quality of life and sexual functioning after cervical cancer treatment: a long-term follow-up study.

OBJECTIVE: The purpose of the study was to investigate the long-term treatment side effects on the quality of life (QoL) and sexual functioning of cervical cancer survivors undergoing different treatment regimens. METHODS: QoL and sexual functioning were measured using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire, the Cervix Cancer Module, and the Sexual Activity Questionnaire. RESULTS: One hundred twenty-one cervical cancer survivors (63 Surgery, 38 Surgery/CT, and 20 Surgery/RT) participated. Patients in the Surgery/RT Group reported significantly worse QoL outcomes (lower scores on physical, role, cognitive, and social functioning) compared with patients in the Surgery Group or patients in the Surgery/CT Group. The level of symptoms such as nausea/vomiting, pain, appetite loss, frequent urination (p=0.019), leaking of urine (p=0.015), and the feeling of a tight vagina (p=0.018) was significantly higher in irradiated patients. Concerning sexual functioning, patients in the Surgery/RT Group reported a significantly lower sexual activity rate compared with women in the Surgery Group or women in the Surgery/CT group (p<0.05). However, there were no statistically significant differences concerning sexual pleasure and sexual discomfort among the three treatment groups (p>0.05). CONCLUSIONS: Cervical cancer survivors treated with adjuvant radiotherapy are more likely at risk for impaired QoL. Survivors treated with surgery or adjuvant chemotherapy return to a similar level of QoL as women without a history of cancer. Although the sexual activity rate is lower in irradiated patients their sexual pleasure is similar to patients after surgery and chemotherapy.

Psychosomatic medicine in primary care: influence of training.

BACKGROUND: General practitioners (GPs) are often confronted with patients presenting somatic symptoms presumed to be decisively modulated by psychosocial factors. OBJECTIVES: We aimed to explore GPs' reported clinical routine in dealing with these patients according to the GPs' level of training in psychosomatic medicine. METHODS: A structured postal questionnaire survey was conducted among all Austrian GPs with a standardized training background in psychosomatic medicine (three levels of training; duration between one and six years) as well as in a random national sample of Austrian GPs without such training, resulting in four study subgroups. RESULTS: Respondents estimated that between 20% and 40% of their patients presenting somatic symptoms need psychosocial factors to be addressed. Study subgroups differed significantly concerning their reported diagnostic and therapeutic routine behavior patterns. Some diagnostic approaches such as clarification of lay etiology increased linearly with the level of training. The proportion of patients receiving corresponding treatment in the GP's own practice was also reported to increase with the level of training (no training: 35%, levels one and two: 46%, level three: 54%), although all subgroups estimated that over 20% of patients do not receive any corresponding treatment. CONCLUSIONS: Results point at the clinical relevance of a general training in psychosomatic medicine in primary care. They also suggest specific training effects that need to be substantiated in observational studies.

The EORTC QLQ-CX24 cervical cancer-specific quality of life questionnaire: psychometric properties in a South Asian sample of cervical cancer patients.

OBJECTIVE: The cervical cancer-specific Quality of Life module of the European Organization for Research and Treatment of Cancer, EORTC QLQ-CX24, was recently validated in an international field study that did not include cervical cancer patients from South Asia. The aim of our study was to assess the psychometric properties of the instrument in a sample of cervical cancer patients from Sri Lanka to assess its suitability for use in the South Asian region. METHODS: One hundred and twelve newly diagnosed patients with cervical cancer completed the translated version of the QLQ-CX24 in a cross-sectional validation study. Psychometric evaluation assessed the instrument for scale structure, scale reliability, validity and acceptability. RESULTS: The QLQ-CX24 was found to be patient-friendly with high compliance and low missing data. Only a few patients needed assistance for completion. Overall results for multitrait scaling analysis confirmed the scale structure although some items of the symptom experience scale exhibited problems regarding item-scale correlations with its own scale. Cronbach's alpha coefficients for internal consistency ranging from 0.63 to 0.79 confirmed scale reliability. Construct validity was confirmed in two ways: the inter-scale correlations were statistically significant (p<0.01) and their magnitude moderate (r = 0.52-0.58) while the scales and single-item measures were able to discriminate between subgroups of patients differing with regard to treatment status. CONCLUSION: The translated version of the QLQ-CX24 is a reliable and valid instrument to measure cervical cancer-specific Quality of Life in Sri Lanka. The overall results are in line with the findings of the international field study.

A new instrument to describe indicators of well-being in old-old patients with severe dementia--the Vienna List.

BACKGROUND: In patients with very severe dementia self-rating of quality of life usually is not possible and appropriate instruments for proxy-ratings are not available. The aim of this project is to develop an instrument of clinical proxy-ratings for this population. METHODS: Using electronic instruments, physicians and nurses recorded patient behaviour and changes of behaviour over a period of one year. Based on these data a list of 65 items was generated and subsequently allocated to 14 categories. This list was tested in 217 patients (61-105 yrs) with dementia diagnosed according to ICD-10 by both physicians and nurses. The severity of dementia was assessed by means of the Global Deterioration Scale (GDS) and the Brief Cognitive Rating Scale (BCRS). The Spitzer-Index (proxy-rating) was used as a global quality of life measure. Activity of daily living was rated using the Barthel Index. RESULTS: A factor analysis of the original 65 items revealed 5 factors (communication, negative affect, bodily contact, aggression, and mobility). By stepwise removing items we obtained satisfactory internal consistencies of the factors both for nurses' and physicians' ratings. The factors were generally unrelated. The validity of the instrument was proven by correlations of the factors communication and mobility with the Brief Cognitive Rating Scale (BCRS) and the Barthel-Index. CONCLUSION: The results demonstrate the reliability and validity of the Vienna List as a proxy rating measurement of quality of life in patients with severe dementia. The psychometric properties of the scale have to be proved in further studies.

Validation of the Polish version of the EORTC QLQ-OV28 module for the assessment of health-related quality of life in women with ovarian cancer.

The aim of our study was to undertake a prospective validation study of the Polish version of the EORTC ovarian cancer (EORTC QLQ-OV28) module used together with the EORTC QLQ-C30. The translated module was pilot-tested according to the EORTC guidelines. Patients with histological confirmation of ovarian cancer were eligible for the study. All patients filled out the Polish version of the EORTC QLQ-OV28, the EORTC QLQ-C30 and a demographic questionnaire. Standard validity and reliability analyses were performed. One-hundred and forty patients agreed to take part in the study (mean age ± standard deviation: 63.3 ± 10.2 years). Cronbach's alpha coefficients showed positive internal consistency (0.78-0.91). Interclass correlations for the EORTC QLQ-OV28 ranged from 0.77 to 0.93 and proved appropriate test-retest reliability. Satisfactory convergent and discriminant validity in multi-trait scaling analyses was seen. The Polish version of the EORTC QLQ-OV28 module proved to be a reliable and valid tool for measuring health-related quality of life in patients with ovarian cancer.

Trends in translation requests and arising issues regarding cultural adaptation.

Quality of life has become an important end point in clinical trials and academic studies. The questionnaires developed by the European Organisation for Research and Treatment of Cancer Quality of Life Group are widely used to measure quality of life in cancer patients. The expanding geographical coverage of current studies and trials implies a continuous rise in requests for new language versions of the questionnaires. Together with normal linguistic problems in translation, cultural differences come into play, especially in translations into non-European languages. Two types of such problems can be differentiated: first, specific issues related to culturally dependent activities or phenomena; second, topical issues related to taboos. These translation challenges have to be carefully addressed to ensure the equivalence and validity of the final questionnaires.

Randomized study of the Arbeitsgemeinschaft Gynaekologische Onkologie Ovarian Cancer Study Group comparing quality of life in patients with ovarian cancer treated with cisplatin/paclitaxel versus carboplatin/paclitaxel.

PURPOSE: The objective of this study was to compare the quality of life (QoL) of ovarian cancer patients treated with paclitaxel/carboplatin (TC) versus paclitaxel/cisplatin (PT) and to determine the impact of treatment toxicity on the various QoL domains. PATIENTS AND METHODS: In this phase III trial, 798 patients with ovarian cancer stages IIB-IV were randomly assigned to receive TC or PT. The primary end point was progression-free survival; secondary end points included toxicity, QoL, and response to treatment. Patients completed the European Organisation for Research and Treatment of Cancer QLQ-C30 before treatment, within 3 days before the second and the fourth chemotherapy cycle, and 3 weeks after completion of chemotherapy. RESULTS: Previously reported data showed that patients undergoing TC or PT did not differ in progression-free survival and overall survival. However, the TC arm was superior, indicating a better overall QoL compared with the PT arm. Controlling for toxicity and age, a significant treatment by assessment time interaction was found for four QoL functioning scales and three symptoms scales. Patients in the TC arm showed better means scores after treatment on overall QoL (P = .012), physical functioning (P = .012), role functioning (P = .005), and cognitive functioning (P = .024), compared with the PT arm. Concerning symptom experience, patients undergoing TC showed less nausea and vomiting (P < .001), less appetite loss (P < .001), and less fatigue (P = .033) after completion of treatment compared with patients undergoing PT. CONCLUSION: The TC regimen achieved better QoL outcomes compared with the PT regimen. Thus, clinicians may consider replacing cisplatin with carboplatin when treating ovarian cancer patients with chemotherapy.

The European Organization for Research and Treatment of Cancer (EORTC) Quality-of-Life questionnaire cervical cancer module: EORTC QLQ-CX24.

BACKGROUND: The authors report on the development and validation of a cervical cancer module for the European Organization for Research and Treatment of Cancer (EORTC) Quality-of-Life (QoL) questionnaire (QLQ), which was designed to assess disease-specific and treatment-specific aspects of QoL in patients with cervical cancer. METHODS: The cervical cancer module (EORTC QLQ-CX24) was developed in a multicultural, multidisciplinary setting to supplement the EORTC QLQ-C30 core questionnaire. The QLQ-C30 and the cervical cancer module were administered to 346 patients with cervical cancer who underwent radical hysterectomy and received radiotherapy and chemotherapy. Psychometric analyses were performed by using data from 2 independent samples. RESULTS: The QLQ-CX24 consists of 3 multiitem scales and 5 single-item scales. Multitrait scaling analyses revealed high internal consistencies for the subscales with Cronbach alpha coefficients ranging from .72 to .87 (Symptom Experience, .72; Body Image, .86; Sexual/Vaginal Functioning, .87). Convergent and discriminant validity were fulfilled with scaling errors below 3%. The QLQ-CX24 was capable of discriminating between clinical subgroups. All items exhibited good compliance with <3% missing values. Most patients completed the EORTC QLQ-C30 and the QLQ-CX24 in <15 minutes (86%), and many did not require any assistance to complete the questionnaires (65%). CONCLUSIONS: The current psychometric analyses supported the content and construct validity and the reliability of the EORTC QLQ-CX24 module. This newly developed module is a useful instrument for assessing the QoL of patients who are treated for cervical cancer both in clinical trials and in clinical practice.
