Cronbach's alpha

The Beck Depression Inventory (BDI), created by Beck, Ward, Mendelson, Mock, and Erbaugh (1961) is one of the most widely used self-report instruments for psychiatric populations that assesses depression through the depth or severity of depressive symptoms. The BDI contains 21 items that are rated on a 4-point scale (0-3) which reflect increasing symptom severity and cover areas of depressive symptomology including affective, cognitive, motivational, and physiological symptoms (Bumberry et al.,…

370 surveys. At this point, I do not know what the response rate is typically for this demographic as it is not specified. In order to maintain reliability in this study, Cronbachs’ alpha will be utilized, with compute software to calculate the data. As Polit and Beck (2012) remark, coefficient alpha or Cronbach’s alpha is the most widely used method for evaluating consistency. This is our check for reliability which works for this tool because it can be used for tests that have no right answer,…

When individuals hear the word “addiction” they immediately think of alcohol or drugs. What most people are not aware of is that addiction can derive from numerous factors such as tanning and that can be even more of an issue at times. According to Skin Cancer Foundation (2015), “More people develop skin cancer because of tanning than develop lung cancer because of smoking”. Since tanning has grown to become more addictive there has been a study that was conducted for the purpose of measuring…

When advanced practice registered nurses (APRNs) complete their graduate program and are ready to start their first job, it is an exciting time! Unfortunately, as these practitioners leave the comforts of academia to enter the workplace, feelings of stress and insecurity are frequently reported (Kelly & Mathews, 2001; Valdes-Pierce, 2004). The transition can be both challenging and overwhelming (Gearhart, 2011). Bahouth and Esposito-Herr (2009) reported survey results of newly graduated nurse…

Cronbach coefficient α was used to assess the degree of homogeneity of the items within each scale. It indicates the extent to which each scale is internally consistent. According to Dorneyi “Internal consistency reliability is measured by the Cronbach Alpha coefficient (named after its introducer, L. J. Cronbach). This is a figure ranging between 0 and +1, and if it proves to be very low, either the particular scale is too short or the items have very little in common. Internal consistency…

measured with the scale based on the Center for Epidemiologic Studies – Depression Scales (CES-D) (Radloff, 1977). This scale has been widely accepted to measure depression among older adults (Haringsma, Engels, Beekman, & Spinhoven, 2004). The Cronbach's Alpha is .825. Depression symptoms provided by the WLS were measured by having the participants report the number of days in the past week (0-7days) that they experienced each of twenty depression symptoms. For the current study, participants’…

scores the scale variable was updated bringing the total from 15 questions to 11. After conducting a discriminative analysis, a Cronbach’s alpha was conducted this refers to a measure used to determine the reliability or consistency of a scale (using and interpreting Cronbach 's alpha, 2016), for a Cronbach 's alpha to be significant it has to be above 0.7, a Cronbach 's alpha of .126 was found, this shows that the items on the scale are measuring the same thing. Validity analysis consists of…

The “Model Minority Myth,” Mental Health Stigma, and Help Seeking Attitudes Within Asian Subgroups in the United States Georgette Estilo 1236947 Brunel University September 18, 2015 Abstract Acknowledgements Table of Contents Introduction The widely popular belief that Asians are “smart” and “always excel in math” are a few of the positive stereotypes that encompass the idea of the “model minority myth.” Few studies have explored the way the endorsement of positive…

a later date. Then, if the results of our test matches the results of the FFPI, our test would then have predictive validity. The other downside of our test is that it has a relatively low internal consistency. Using a split-half method, our Cronbach’s Alpha was a low 0.4. To obtain a higher internal consistency, we would need to further revise on our test items to remove items that does not seem to measure what it purports to…

Being a social worker or counselor is the occupation that I have chosen. I chose the DVI test. This test would help me when I have clients that are court ordered to take a domestic violence test. This will assist me in helping to see where the client is having problems and try to prevent it if possible or let them know what treatment would be necessary for the client. I know that I will be working with all types of people, and I have chosen the DVI test which is a risk assessment tool and is…
