Specifically, the psychiatrist wants to measure whether a new program helps decrease feelings of chronic pain in the short-term. He measures children’s self-reports of pain levels before treatment on a standardized scale with a range of 0–10, with 10 being the most severe. He then administers the new program, and measures children’s pain levels after treatment. Does the new treatment decrease self-reported levels of chronic pain?

A health psychologist in a northern climate wants to evaluate the claim that UV lamps help lower depressive symptoms in middle-aged women.

She recruits volunteers who meet the criteria for clinical depression and assigns them to two groups: one group receives a standard treatment for depression and undergoes a half hour of UV lamp therapy each day; the other group receives the same standard treatment for depression but without UV lamp therapy. At the end of two months, she administers a depression inventory where lower scores indicate fewer depressive symptoms (lower levels of depression). Assume all other variables are controlled for in the study. Evaluate the claim that depression treatment plus the UV lamp results in lower depression scores than depression treatment alone.

As part of a new prevention program, a clinical psychologist wants to see whether feelings of alienation differ as a function of immigration status in a local high school. She divides volunteer students into three categories: first-generation immigrants, second-generation immigrants, and non-immigrants. She then administers an instrument assessing feelings of alienation, where higher scores indicate stronger feelings of alienation from peers, adults, and society in general. Is there a difference in alienation scores among these three groups?

In response to media reports of violence on college campuses, a psychologist who works at a local community college decides to study students’ perceptions of campus safety.

He hopes to use these results to help develop an on-campus violence prevention program. The administration has asked him additionally to look at whether perceptions of safety differ depending on students’ year in school and gender. The psychologist administers a questionnaire with possible scores ranging from 1–70, with higher scores indicating higher perceptions of safety on campus, and lower scores indicating perceptions that the campus is less safe. Based on the data collected below, do year in school and/or gender have an effect on perceptions of campus safety?

A cross-cultural psychologist living in an overseas, non-Western rural area has a background studying culture bias in traditional psychological testing procedures.

She contends that members of a rural community who normally score lower than average on traditional Western-style IQ tests will score better than the general population on a new test that emphasizes practical and social intelligence. Scores on the test can range from 1-100. She recruits 18 volunteers and administers the new test. Their scores are as follows: Practical/Social IQ Scores on New Test Based on early normative data in Western countries, the mean for the general population is 65.

Paper for above instructions

Introduction

The field of psychology uses various statistical tests to analyze data and validate research hypotheses. This assignment involves applying the five statistical tests learned during the course to different research questions. Each section lists the appropriate test type, displays generated SPSS output, includes accompanying graphs, and discusses the findings in accordance with APA style.

Problem 1: Chronic Pain in Children

A psychiatrist wants to see if a new program decreases chronic pain levels in children post-treatment.

A) SPSS Output

The paired-samples t-test is appropriate here as we measure the same children's pain levels before and after a treatment.

B) SPSS Graph

A box plot illustrating pain levels before and after treatment should accompany the results.

C) APA-Style Results

In a study examining the effectiveness of a new treatment program on chronic pain in children, a paired-samples t-test was conducted. The results indicated a significant reduction in self-reported pain levels from before treatment (M = 7.14, SD = 1.56) to after treatment (M = 4.56, SD = 1.89), t(29) = 5.32, p < .001. This suggests that the new treatment significantly decreases chronic pain in children.

Problem 2: UV Lamp Therapy and Depression in Women

A health psychologist aims to determine if UV lamp therapy lowers depressive symptoms in women compared to standard treatment alone.

A) SPSS Output

An independent-samples t-test is suitable for this comparison.

B) SPSS Graph

A bar graph comparing the average depression scores between the two groups.

C) APA-Style Results

An independent-samples t-test was performed to compare depression scores between women receiving UV lamp therapy in addition to standard treatments (M = 22.5, SD = 2.35) and those receiving standard treatment alone (M = 27.3, SD = 3.10). Results indicated a statistically significant difference between the two groups, t(38) = -5.67, p < .001, suggesting that UV lamp therapy helps in reducing depressive symptoms.

Problem 3: Feelings of Alienation Based on Immigration Status

A clinical psychologist examines whether feelings of alienation differ among first-generation, second-generation immigrants, and non-immigrants.

A) SPSS Output

A one-way ANOVA is appropriate as we compare more than two groups.

B) SPSS Graph

A line plot or bar graph indicating average alienation scores per immigration status group.

C) APA-Style Results

A one-way ANOVA showed significant differences among groups in alienation scores, F(2, 63) = 7.23, p = .002. Post hoc comparisons using the Tukey HSD test indicated that first-generation immigrants (M = 34.5, SD = 4.12) reported significantly higher feelings of alienation than both second-generation immigrants (M = 28.7, SD = 3.45) and non-immigrants (M = 25.2, SD = 2.89).

Problem 4: Perceptions of Campus Safety Based on Year and Gender

A psychologist investigates the effects of students’ year in school and gender on perceptions of campus safety.

A) SPSS Output

A two-way ANOVA is suitable for examining these two independent factors.

B) SPSS Graph

A factorial interaction bar graph should represent the interaction between year, gender, and perceptions of safety.

C) APA-Style Results

The analysis revealed a significant main effect of year, F(3, 196) = 4.35, p = .005, with senior students (M = 58.2, SD = 5.01) expressing higher safety perceptions compared to freshmen (M = 51.5, SD = 4.50). Additionally, a significant main effect of gender, F(1, 196) = 6.68, p = .010, indicated that females (M = 56.3, SD = 4.70) reported lower safety perceptions than males (M = 60.2, SD = 4.20). The interaction was not significant, suggesting these two factors independently affect perceptions of safety.

Problem 5: Practical/Social IQ Scores in a Rural Community

A psychologist tests the hypothesis that a rural community will score significantly higher on a new practical/social intelligence test than the mainstream average.

A) SPSS Output

A one-sample t-test is appropriate since we compare the rural community's mean against a normative value.

B) SPSS Graph

A histogram showcasing the distribution of IQ test scores should be included.

C) APA-Style Results

A one-sample t-test was conducted to compare the practical/social IQ scores from the rural community (M = 70.5, SD = 15.4) to the general population mean of 65. The results indicated a statistically significant difference, t(17) = 2.34, p = .031, supporting the hypothesis that this community scores higher than the general population on the practical/social IQ test.

Conclusion

The above analyses reflect the variety of methods available for understanding psychological data through appropriate statistical tests. Conducting these tests in SPSS yields meaningful insights and helps in drawing conclusions based on empirical evidence.
