Seclusion: the association with diagnosis, gender, length of stay and HoNOS-secure in low and medium secure inpatient mental health service

The use of seclusion is controversial. Using routinely collected data from low and medium secure service provider in the United Kingdom (n = 347) this study compared secluded and non-secluded Asperger’s syndrome, paranoid schizophrenia, organic personality disorder and emotionally unstable personality disorder patients. Analysis revealed that secluded patients were younger but did not differ on length of stay. Scores on the HoNOS-secure improved from entry to discharge on all diagnostic categories, indicating sensitivity to change. However, secluded patients with paranoid schizophrenia did not improve on the secure scale or personal and emotional well-being sub-scale factors, indicating HoNOS-secure should be used with caution in discharge decisions. Findings indicate that HoNOS-secure do not capture the factors linked to the use of seclusion in organic personality disorder and Asperger’s syndrome. HoNOS secure results outline differing needs and progress in the four diagnostic groups. Seclusion did not affect recovery as measured by HoNOS-secure clinical scale, providing evidence opposing the view that seclusion plays a major contribution to delaying recovery.

Indirect Self-Destructiveness in Women who Experience Domestic Violence

Lives of people experiencing domestic or/and intimate partner violence abound in many unpleasant events and physical and psychological suffering, which affects their psychosocial functioning. The aim of this study was to explore indirect self-destructiveness as a generalised behavioural tendency and its manifestations in women experiencing domestic violence. The “Chronic Self-Destructiveness Scale” (CS-DS) was used to study two groups of women: 52 women aged 30–65 years (mean age: 40.15) using assistance of the Crisis Intervention Centre due to experienced domestic violence (V group) and 150 well-matched women not experiencing domestic violence (NV group). Women suffering domestic violence (V) obtained significantly higher scores than women not experiencing domestic violence (NV) for both the general index and a majority of CS-DS subscales; it was only for the A1 (Transgression and Risk) subscale that they achieved somewhat lower scores. Correlation coefficients between particular CS-DS subscales in the V group were higher than in the NV group; there were also certain differences in coefficients between the groups. Subscale factor analysis results were different too: only one factor was isolated in the V group while two were distinguished in the NV group. It can be inferred from the results that the intensity of indirect self-destructiveness as a generalised behavioural tendency as well as of most its categories was higher in women experiencing domestic violence. Tendencies and categories of indirectly self-destructive behaviours in women suffering domestic violence were more closely connected with one another, and the internal coherence of indirect self-destructiveness in those women might also be higher.

Development of a Scale to Measure Educators’ Practice in Teaching Self-Determination

<p style="text-align:justify">The purpose of this study was to develop a scale for assessing teachers’ self-determination instruction and to test the validity and reliability of this tool. The subjects included 315 teachers recruited from elementary and junior high schools nationwide in Taiwan. The Teaching Self-Determination Scale (TSDS) developed in this study aimed at assessing the extent to which educators teach students knowledge and skills related to self-determination. The 24-item TSDS is comprised of four subscales including Self-Realization, Psychological Empowerment, Self-Regulation, and Autonomy. Data collected were analyzed using descriptive statistics, correlation analyses, t tests, and factor analyses. Findings showed that the TSDS has satisfactory psychometric properties. The internal consistency reliability coefficients (Cronbach’s α) ranged from .76 to .93, while the test-retest coefficients ranged from .71 to .87. Findings of the exploratory factor analysis showed that the four TSDS subscale factors can be reasonably extracted, which can explain 59.7% of the total item variance. The confirmatory factor analysis results further indicated a good fit between the measurement model and the sample data (GFI = .96, AGFI = .91, RMSEA = .08, NFI = .97, RFI = .93, IFI = .98, TLI = .95, CFI = .98). Suggestions are provided for future research.</p>

Development and validation of a novel scale for measuring interpersonal factors underlying injection drug using behaviours among injecting partnerships

BackgroundPeople who inject drugs with sexual partners or close friends have high rates of syringe/ancillary equipment sharing and HIV and hepatitis C virus (HCV) infection. Although evidence suggests that interpersonal factors underlie these higher risk profiles, there is no quantitative measure of how interpersonal factors operate within injecting relationships. We aimed to develop and validate a quantitative scale to assess levels of injecting drug-related interpersonal factors associated with risky injecting behaviours within injecting partnerships. MethodsWe conducted qualitative interviews with 45 people who inject drugs (PWID) who reported having injecting partners to inform item development, and tested these items in a quantitative study of 140 PWID from San Francisco, USA, to assess internal reliability (Cronbach’s alpha) and validity (convergent, and discriminant validity). ResultsWith results from the qualitative interview data, we developed the Interpersonal Dynamics in Injecting Partnerships (IDIP) scale with 54 final items for 5 subscales of injecting-related interpersonal factors. Exploratory factor analysis revealed 5 factors (“trust”, “power”, “risk perception”, “intimacy”, and “cooperation”) with eigenvalues of 14.32, 6.18, 3.55, 2.46, and 2.14, explaining 57% of the variance, and indicating good internal reliability (alpha: 0.92–0.68). Strong convergent validity was observed in bivariate logistic regression models where higher levels of trust, intimacy, and cooperation within partnerships were positively associated with partners sharing needles and injecting equipment, whereas higher levels of power and risk perception were negatively associated with partners sharing needles and injecting equipment. ConclusionsThese findings offer strong evidence that the IDIP scale provides a psychometrically sound measure of injecting drug-related interpersonal dynamics. This measurement tool has the potential to facilitate additional investigations into the individual and collective impact of trust, intimacy, power, cooperation, and risk perception on injection drug using behaviours and engagement in HIV and HCV testing and treatment among PWID in a variety of settings.

Reasons for Marijuana and Tobacco Co-use Among Young Adults: A Mixed Methods Scale Development Study

ABSTRACTBackground: Marijuana-tobacco co-use has increased recently, particularly in young adults. Objectives: We conducted a mixed-methods study to: (1) examine reasons for co-use; and (2) develop a scale assessing reasons for co-use among participants in a longitudinal cohort study of 3,418 students aged 18-25 from 7 Georgia colleges and universities. Methods: Phone-based semi-structured interviews were conducted in Summer 2015 among 46 current (past 30-day, n = 26) or lifetime (n = 20) marijuana users. Subsequently, scale items were developed and included at Wave 3. Participants reporting past 4-month tobacco and marijuana use (n = 328) completed the Reasons for Marijuana-Tobacco Co-use section. Results: Per qualitative data, reasons for marijuana-tobacco co-use included synergistic effects, one triggering or preceding the other's use, using one to reduce the other's use, co-administration, social context, and experimentation. The survey subsample included 37.1% who used cigarettes, 30.4% LCCs, 9.4% smokeless, 23.7% e-cigarettes, and 30.4% hookah. Four subscale factors emerged: (1) Instrumentality, indicating synergistic effects; (2) Displacement, indicating using one product to reduce/quit the other; (3) Social context, indicating use in different settings/social situations; and (4) Experimentation, indicating experimentation with both but no specific reasons for co-use. These subscales demonstrated distinct associations with tobacco type used; nicotine dependence; marijuana and alcohol use frequency; tobacco and marijuana use motives, respectively; perceptions of tobacco and marijuana; and parental and friend use. Including these subscales in regressions predicting nicotine dependence and days of marijuana use significantly contributed to each model. Conclusions: These findings might inform theoretical frameworks upon which marijuana-tobacco co-use occurs and direct future intervention studies.

Talking About Death With Terminally-Ill Cancer Patients: What Contributes to the Regret of Bereaved Family Members?

ContextTalking about death is an important issue for terminally-ill cancer patients and their families. Little is known about how often and which bereaved families regret not having talked about death with their deceased loved one. ObjectivesTo explore the prevalence of a regret of not having talked about death with a deceased loved one among bereaved family members of adult cancer patients, and to systematically explore factors contributing to their regret. MethodsWe conducted a nationwide survey of 999 bereaved families of cancer patients admitted to 133 inpatient hospices in Japan and surveyed families' regret on talking about death. Exploratory analyses identified the underlying structures of process, option, and outcome subscales of factors contributing to regret. ResultsAmong 678 bereaved families (response rate 68%), 224 (33%) regretted not having talked about death sufficiently, whereas 40 (5.9%) conversely regretted having talked about death. Three process factors (“prognostic disclosure to patient” [β = 0.082, P = 0.039], “upsetting of patient and family” [β = 0.127, P = 0.001], and “family's sense of uncertainty about when to act based on terminal awareness” [β = 0.141, P = 0.000]) and an outcome factor (“having achieved a good death” [β = −0.152, P = 0.000]) contributed to the regret of talking insufficiently. ConclusionA third of bereaved families of adult cancer patients regretted not having talked about death sufficiently. Clinicians may minimize this regret by facilitating a shared understanding of the disease and prognosis, advising families explicitly when to talk based on terminal awareness, providing continuous emotional support, and validating their decision on talking about death.

A service evaluation of psychodynamic psychotherapy for people with intellectual disabilities

The evidence base for psychodynamic psychotherapy for people with intellectual disabilities (ID) is mainly made up of case studies with a small number of open trials without control (Beail, 2016) and the development of the evidence base for psychological therapies is a priority. In this service evaluation, we estimated the significance and effect size of psychodynamic intervention in 66 cases from the time of assessment to case closure, using the Health of the Nation Outcome Scales for Learning Disability (HoNOS-LD). A significant and sizeable effect from assessment to case closure was detected on HoNOS-LD Total Score, with similar effects on subscale Factor Scores. A waiting list control condition for a smaller subset did not find significant overall change, and cases remaining within the service following intervention showed no deterioration after therapy. A relatively low number of sessions was required on average (13.7; median=8) but a dose-effect relationship was observed with more change associated with more sessions. We consider the shortcomings of this study and make recommendations for improved design of further studies.

COMPARISON AND IDENTIFICATION OF FACTORS INFLUENCING THE FLAVORS OF ENTERAL NUTRITION AGENTS

Objective:The flavor of an enteral nutrition formula affects medication adherence as well as patient’s nutritional status and therapeutic efficiency on the major pathology. Therefore, it is important for medical professionals to understand the flavors of enteral nutrition formulas. This study aimed to evaluate the flavors of enteral nutrition formulas and examine the factors influencing these flavors. Methods:A total of 304 students in a pharmaceutical department were subjected to a semantic differential sensory evaluation in which they compared the flavors of digestion and semi-digestion enteral nutrition formulas using a five-point scale. In addition, factors related to good flavor were extracted via factor analyses, and subjected to a covariance structure analysis.Results:In the flavor comparison between digestion and semi-digestion nutrition formulas, semi-digestion nutrition agents scored significantly higher than digestion nutrition formulas did (Welch's t test, P < 0.001, 95% confidence interval [CI] = 0.69–0.99). The factor analyses extracted three subscales of factors related to good flavor: impression of taking, feeling of presence and sense of richness. In a path analysis model to determine the influence of these factor subscales on flavor, impression of taking feeling of presence were found to have significant influences (index of goodness of fit: χ2 = 474.883, df = 62, P < 0.001, GFI = 0.938, AGFI = 0.909, RMSEA = 0.079).Conclusion:Flavor affects medication adherence to enteral nutrition. Therefore, it is important for medical professionals to understand the factors that influence flavor and thus provide patients with better nutrition formulas.

Australian undergraduate nursing students’ opinions on mental illness

Objective: To determine second year Bachelor of Nursing students’ opinions on mental illness and relationship with demographic data for the purpose of curriculum development. Design: The present study is a pilot study for a larger project which will investigate undergraduate nursing student opinions across the duration of their undergraduate degree at an Australian university. The ‘Student Opinions of Mental Illness Scale’, a 53 point Likert type questionnaire was used in a sample of second year nursing students to investigate their opinions of mental illness. Setting: Metropolitan nursing school in Victoria, Australia. Subjects: 133 second year undergraduate Bachelor of Nursing students’. Main outcome measures: Student opinions based on Likert responses. Results: The study revealed that student experiences, education, employment history of country of birth may impact upon student opinions of mental illness. Conclusion: Overall, students were found to have a generally neutral opinion about mental illness except in the sub-scale factors of benevolence, mental hygiene ideology and interpersonal aetiology where students held less positive opinions. Knowing the student populations opinions about a subject matter can assist academics to direct and focus their efforts to improve those opinions in those areas.

Adaptation of the Practice Environment Scale for military nurses: a psychometric analysis

The aim of this study was to confirm the psychometric properties of Practice Environment Scale of the Nursing Work Index in a military population. This study also demonstrates association rule analysis, a contemporary exploratory technique. One of the instruments most commonly used to evaluate the nursing practice environment is the Practice Environment Scale of the Nursing Work Index. Although the instrument has been widely used, the reliability, validity and individual item function are not commonly evaluated. Gaps exist with regard to confirmatory evaluation of the subscale factors, individual item analysis and evaluation in the outpatient setting and with non-registered nursing staff. This was a secondary data analysis of existing survey data. Multiple psychometric methods were used for this analysis using survey data collected in 2014. First, descriptive analyses were conducted, including exploration using association rules. Next, internal consistency was tested and confirmatory factor analysis was performed to test the factor structure. The specified factor structure did not hold; therefore, exploratory factor analysis was performed. Finally, item analysis was executed using item response theory. The differential item functioning technique allowed the comparison of responses by care setting and nurse type. The results of this study indicate that responses differ between groups and that several individual items could be removed without altering the psychometric properties of the instrument. The instrument functions moderately well in a military population; however, researchers may want to consider nurse type and care setting during analysis to identify any meaningful variation in responses.

Examining the Factor Structure of the Self-Compassion Scale in Four Distinct Populations: Is the Use of a Total Scale Score Justified?

ABSTRACTThis study examined the factor structure of the Self-Compassion Scale (SCS) using a bifactor model, a higher order model, a 6-factor correlated model, a 2-factor correlated model, and a 1-factor model in 4 distinct populations: college undergraduates (N = 222), community adults (N = 1,394), individuals practicing Buddhist meditation (N = 215), and a clinical sample of individuals with a history of recurrent depression (N = 390). The 6-factor correlated model demonstrated the best fit across samples, whereas the 1- and 2-factor models had poor fit. The higher order model also showed relatively poor fit across samples, suggesting it is not representative of the relationship between subscale factors and a general self-compassion factor. The bifactor model, however, had acceptable fit in the student, community, and meditator samples. Although fit was suboptimal in the clinical sample, results suggested an overall self-compassion factor could still be interpreted with some confidence. Moreover, estimates suggested a general self-compassion factor accounted for at least 90% of the reliable variance in SCS scores across samples, and item factor loadings and intercepts were equivalent across samples. Results suggest that a total SCS score can be used as an overall mesure of self-compassion.

Confirmatory factor analysis of autism and schizophrenia spectrum traits

The relationship between the Autism Spectrum Quotient (AQ) and Schizotypal Personality Questionnaire (SPQ) data has consistently shown overlap in the social and interpersonal domains. Factor analyses of the AQ and SPQ subscales support this overlap with the emergence of a shared AQ and SPQ subscale factor as the largest common element. This study investigated, at the item level, the factor structure of the AQ and SPQ. Exploratory and confirmatory factor analyses were conducted on the AQ and SPQ responses of 1670 participants (aged 18–40, 1243 females, 427 males). Seven factors cumulatively explained 40.56% of the data. Of these, four represented shared traits (named Odd Behaviour, Relationship Disinterest, Cue Interpretation, Social and Communication Discomfort), one was a more specific autistic tendency (named Fixation with Details), and two factors were more specific to the psychotic dimension of schizotypy (named Paranoia/Suspiciousness and Hallucination/Delusional Experiences). These findings demonstrate that a set of symptom traits is present in both the autism and schizophrenia spectra. The findings of this study have important clinical implications in terms of future research, diagnosis and treatment of autism and schizophrenia spectrum disorders.

Attitudes to Body Image in Athlete and Non-Athlete Female Students

The aim of this study was to compare attitudes to body image in athlete and non-athlete female students. For this purpose, 200 athlete and non-athlete female students were randomly selected and took part in the present study. Questionnaires were distributed among volunteers and finally, 160 questionnaires were collected and used. Self-Body image was assessed using the Multidimensional Body-Self Relations Questionnaire (MBSRQ) included 69 items, 7 factors subscales and 3 additional subscales. Variables regarding athletes and non-athletes were compared using independent sample t test. Research findings showed that the scores of some subscales such as “Appearance Orientation” (p<0.05), “Health Evaluation” (p<0.01), “Health Orientation” (p<0.01) and “Body Areas Satisfaction” (p<0.01) in athletes were significantly higher than those of non-athletes. However, scores of fitness evaluation in non-athletes were significantly higher than athletes (p<0.01). There was no significant difference between the two groups in other subscales. Exercise training appears to improve some subscales of attitudes to body image of female athletes and it can serve as a therapeutic way to enhance the attitudes of non-athlete ones.

Validation of the Chinese Version of the Readiness for Hospital Discharge Scale on Patients Who Have Undergone Laryngectomy.

The Readiness for Hospital Discharge Scale (RHDS) was designed to assess the readiness of patients for discharge. The original English-language instrument has shown high degrees of reliability and validity, but no Chinese version of the scale has been verified. The purpose of this study was to translate the RHDS into Chinese and assess the psychometric properties of this scale on laryngectomy patients in China. The RHDS was translated into Chinese using forward and back translation, semantic equivalence assessment, and pilot testing. The content and construct validity, internal consistency, and internal reliability of the translated scale were assessed using exploratory factor analysis and Pearson correlation analysis. The content validity index of the developed Chinese version of the RHDS was .97, with the content validity indexes of RHDS items ranging between .75 and 1.00. The Cronbach's α coefficient for internal consistency was .97. Exploratory factor analysis revealed a three-factor structural model. All correlations among the three factor subscales were significant. Pearson's correlation coefficients between subscale factors and the total scale ranged from .81 to .97. The Chinese version of the RHDS is a valid and reliable instrument for assessing the discharge readiness of laryngectomy patients in China.

Psychometric Testing of the Student Evaluation of Clinical Educational Environment Inventory in Greek Nursing Students

&lt;p&gt;&lt;strong&gt;INTRODUCTION:&lt;/strong&gt; The need for translation and validation of an assessment tool regarding the&lt;em&gt; &lt;/em&gt;Clinical Learning Environment of nursing students in Greece is imperative, given that inappropriate research tools are frequently used. &lt;strong&gt;Τhe aim&lt;/strong&gt; of this study was to validate and psychometrically test the Greek translation of the Student Evaluation of Clinical Educational Environment (SECEE) Version 3 Inventory, with a sample of senior nursing students during their clinical practice.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;METHODS:&lt;/strong&gt;&lt;em&gt; &lt;/em&gt;Following a formal “forward-backward” method to translate the original SECEE into Greek, the scale was administered to 130 senior students. They also completed the Clinical Learning Environment and Supervision (CLES) Scale. Validity and reliability analyses were performed.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;RESULTS:&lt;/strong&gt;&lt;em&gt; &lt;/em&gt;Cronbach’s alpha coefficient for the SECEE subscales score was 0.89 for Instructor Facilitation of Learning (IFL), 0.84 for Learning Opportunities (LO) and 0.84 for Preceptor Facilitation of Learning (PFL). Test-retest reliability analysis in a subgroup of students (n=40) revealed good short term stability over a two week interval. Confirmatory factor analysis confirmed the three factor subscales for the Greek translation, as in the original scale. Construct validity was supported through the scale’s moderate correlation with CLES subscales, ranged from 0.163 to 0.317 for IFL, from 0.387 to 0.445 for LO and from 0.443 to 0.537 for PFL.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;CONCLUSIONS&lt;/strong&gt;&lt;strong&gt;: &lt;/strong&gt;The Greek version of the SECEE is a psychometrically sound instrument that can be usefully implemented into clinical education to identify appropriate clinical sites and provide information about student perceptions regarding the adequacy of learning opportunities. &lt;strong&gt;&lt;/strong&gt;&lt;/p&gt;

Patient Experience in an Era of Primary Care Transformation: Revisiting the PACIC

Aims and Objective: The validation study of the Patient Assessment of Chronic Illness Care (PACIC) questionnaire suggested a 5-factor structure determined a priori, but subsequent analyses have questioned the validity of the original factor structure. This study analyzed the factor structure of the PACIC using a large and diverse patient sample, and evaluated the identified factors through the lens of recent transformational initiatives in primary care. Convenience samples of adults completed surveys in waiting rooms during clinic visits. Primary care patients with 1 or more chronic illnesses with complete PACIC responses at baseline from 39 clinics (n=1,567) and at follow-up from 36 clinics (n=1,536) participated. Exploratory and confirmatory factor analyses were conducted on baseline and follow-up patient questionnaire data from a cluster randomized controlled trial. Identified factors were evaluated in terms of item loadings, content, reliability, and the extent to which items reflected advances in the delivery of chronic illness care. Analyses supported the use of the PACIC summary score. Although a 5-factor model was retained, factor loadings were different from the original PACIC validation study. All factors had sufficient reliability, but findings suggested potential revisions to enhance the factor structure. It may be time to revise the PACIC to enhance the stability of the subscales (factors) and better reflect recent transformations in the delivery of chronic illness care.

Survey of personality factors and impulsivity in active and non-active elderly men (2012 )

Introduction and purpose: Different personality factors and impulsivity can directly affect life style and behaviors of older people. Therefore, the aim of this study was to compare impulsivity and personality factors in physically active elderly and sedentary individuals. Materials and methods: This comparative correlational study used random stratified sampling method to recruit 90 elderly living at Tabriz city in 2012. Data were collected using five personality factors questionnaire (NEO) and Barrat impulsivity Scale. We used independent sample t-tests, ANOVA and Pearson correlation coefficient to analyze data using SPSS software version 19. Actual data analysis was conducted among only 80 participants (40 active and 40 non-active elders) who completely answered questionnaires. Findings: Findings from the present study revealed a significant difference in openness personality (p=0.013) among active vs. sedentary elderly. There was a direct relationship between impulsivity and Neuroticism (r=0.393, p=0.02) while, there was a significant negative correlation between impulsivity and extraversion (r=-0.320, p=0.013), agreeableness (r=-0.598, p=0.001) and conscientiousness (r=-0/684, p=0.01). Besides, there was a positive significant association between impulsivity and lack of program elements (r=0.272, p=0.037), cognitive impulsivity (r=0.386, p=0.003). In contrast, series of negetaive significant correltion was reported between Neuroticism and extraversion (r=-0.317, p=0.014) agreeableness (r=-0.447, p=0.001) as well as conscientiousness (r=-0528, p=0.001). conclusion: There was no significant difference between subscales of impulsivity and personality factors (except openness) in active and inactive elderly men. However there was a relationship between impulsivity and some of personality factors which can be influenced by several factors, including physical activity.

Adherence to prophylactic treatment in patients with haemophilia in Germany.

Adherence to prophylactic treatment in haemophilia is important for patient outcome. This study analysed the influence of potential impact factors on adherence assessed through the application of the German translation of the VERITAS-Pro questionnaire. All members of the German haemophilia patient organisation (DHG) who suffer from severe or moderate haemophilia and are on continuous prophylactic treatment were asked to complete the VERITAS-Pro questionnaire. Further questions were added regarding the patients' age, severity of haemophilia, type A or B, frequency of prophylaxis, pain level, factor application self or non-self and co-morbidities. Responses of 397 patients on continuous prophylactic treatment, 0-80 years old, were analysed according to several age groups: 0-14, 15-19, 20-59 (20-29 and 30-39) and ≥60 years of age. The mean total VERITAS-Pro score for the whole sample was 36.7 ± 11.7 (range of 24-86). The scores were significantly higher, indicating the poorest adherence, in patients between 20 and 59 years of age (41.1 ± 11.7) compared with the other age groups (30.0-35.7). Adherence to treatment was highest in patients between 0 and 14 years of age in all subscales of the VERITAS-Pro. The following potential risk factors for non-adherence were evaluated in all age groups: organisation suffering (care by a haemophilia centre), severity and type of haemophilia, factor concentrate administration and the presence of co-morbidities. The identification of significant differences between age groups in special subscales of adherence and impact factors offers tailored starting points for improvements of adherence to prophylactic treatment.

Constructing an assessment index system for strategic risk management in coal science and technology enterprises

Coal occupies a dominant position in China’s national economy and is an essential energy source for future industrial development. To inform the efficient and sustainable development of the coal industry, this paper analyzes the sources of strategic risk for coal science and technology enterprises using 3 first-class indicators, 10 second-level indicators, and 37 observation points established through the existing research literature and experience. Moreover, in accordance to the obtained initial index data, the selected indicators have been tested and screened using reliability and membership degree analyses to remove redundant variables, avoid juxtaposition of risk factors at different levels, and reduce the influence of some tiny risk factors for enterprise strategic risk. Then, factor analysis of external environment factor sub-scale was carried out. Factors are extracted according to a standard characteristic value greater than 1. Variables with high coefficients are classified into one factor category; and finally, 3 first-class indicators, 8 second-level indicators, and 37 observation points are reconstructed.
