Create A Table To Group Items Representing A Comm
Week 2 - Assignment: Create a Table to Group Items Representing a Common Concept Instructions Below are statements coming from different psychological scales constructed by different authors; what the scales are measuring nor the number of scales that are represented by these items are identified. Since the psychological variables measured by the items are fairly easily identifiable, create a table in which you will group those items that represent a common concept. Then, invent a construct or variable name for these items. This is an exercise that tests your intuitive abilities to spot the supposedly hidden constructs represented by these items. Consider this assignment as an “armchair” factor analysis.
Items: I feel irritable, easily agitated, and am impatient a few days before my period. I feel anxious watching a teacher work on an algebraic equation on the whiteboard. This is the dreariest time of my life. I am just as happy as when I was younger. My life could be happier than it is now. I have cramps that begin on the first day of my period. I don’t feel good being required to enroll in statistics. I expect some interesting and pleasant things to happen to me in the future. My breasts feel tender and sore a few days before my period. I feel old and somewhat tired. As I look back on my life, I am fairly well satisfied. I hate buying a math textbook. I feel depressed for several days before my period. I have backaches which begin the same day as my period. I don’t like reading and interpreting graphs or charts. I take prescription drug for the pain during my period. I’ve gotten pretty much what I expected out of life. Compared to other people, I get more the share of bad luck. I don’t like being told how to interpret probability statements. For several days before my period I feel exhausted, lethargic or tired. Most of the things I do are boring or monotonous. I’m feel my chest pound when I walk into a math class. I have abdominal pain or discomfort which begins one day before my period. I would not change my life even if I could. I’m anxious when I am waiting to get a math test returned even when I expect to have done well. The pain I have with my period is not intense but a continuous dull aching. I feel weak and dizzy during my period. I feel restless listening to somebody explaining a math formula. As I grow older, things seem better than I thought they would be. I have gotten more of the breaks in life than most of the people I know.

In psychological research, identifying underlying constructs from observed items is vital for understanding complex human behaviors and experiences. This exercise involves analyzing a set of items derived from different scales and grouping them based on their conceptual similarities to infer potential latent variables. Employing a data-driven yet intuitive approach akin to "armchair" factor analysis allows us to hypothesize about the constructs these items represent, informed by psychological theory and contextual interpretation.
Methodology
The items provided encompass a wide array of emotional, physical, and social experiences, particularly centered around menstrual cycles, aging, academic attitudes, and general well-being. The initial step involves reading each item carefully to identify common themes or dimensions that they might measure. This process is qualitative and interpretive, emphasizing coherence and conceptual clarity over statistical procedures.
Grouping of Items: Conceptual Analysis
Through detailed examination, several clusters emerge, each indicative of a broader latent construct. The first group pertains to mood and emotional fluctuations associated with menstrual cycles, characterized by irritability, depression, fatigue, and physical discomfort. These items suggest a construct related to premenstrual or menstrual mood and physical symptoms. Accordingly, we could name this construct “Premenstrual Symptomatology” or “Menstrual-Related Mood and Physical Distress.”
Items included: "I feel irritable, easily agitated, and am impatient a few days before my period," "I feel depressed for several days before my period," "I have cramps that begin on the first day of my period," "My breasts feel tender and sore a few days before my period," "I feel old and somewhat tired," "For several days before my period I feel exhausted, lethargic or tired," "The pain I have with my period is not intense but a continuous dull aching," "I feel weak and dizzy during my period," and "I have abdominal pain or discomfort which begins one day before my period."
The second cluster seems to revolve around attitudes toward academic or intellectual activities, particularly math and statistics, and attitudes towards interpretation and learning. These items reflect cognitive and affective responses toward education, such as dislike or frustration with math, reading graphs, or probability statements, indicating a construct potentially titled “Academic Attitudes Toward Mathematics and Statistics” or “Math and Probability Attitudes.”
Items include: "I don’t feel good being required to enroll in statistics," "I hate buying a math textbook," "I don’t like reading and interpreting graphs or charts," "I don’t like being told how to interpret probability statements," and "I feel anxious watching a teacher work on an algebraic equation on the whiteboard," "I feel restless listening to somebody explaining a math formula," and "I feel my chest pound when I walk into a math class."
The third group appears to represent general life satisfaction and outlook, capturing contentment with life, perceptions of luck, and perspectives on aging and life changes. These items pertain to subjective well-being and life appreciation, perhaps labeled “Life Satisfaction and Outlook.”
Items include: "I look back on my life, I am fairly well satisfied," "I’ve gotten pretty much what I expected out of life," "Compared to other people, I get more the share of bad luck," "As I grow older, things seem better than I thought they would be," "I would not change my life even if I could," and "Most of the things I do are boring or monotonous."
The fourth group involves perceptions of aging and physical health, capturing feelings of being old, tired, and experiencing age-related symptoms. This construct could be designated as “Perceptions of Aging and Physical Health.”
Items include: "I feel old and somewhat tired," "Most of the things I do are boring or monotonous," "I feel my chest pound when I walk into a math class," "I feel weak and dizzy during my period," and "I feel tired or lethargic."
The final cluster addresses emotional and physical responses related to anxiety and distress, especially when anticipating or experiencing difficult situations. This can be termed “Anxiety and Stress Related to Academic and Physical Conditions.”
Items include: "I am anxious when I am waiting to get a math test returned even when I expect to have done well," "I feel anxious watching a teacher work on an algebraic equation," and "I feel restless listening to somebody explaining a math formula."
Summary of Constructed Table
| Group Number | Construct Name | Items Included |
|---|---|---|
| 1 | Premenstrual Symptomatology | I feel irritable, easily agitated, and am impatient a few days before my period; I feel depressed for several days before my period; I have cramps that begin on the first day of my period; My breasts feel tender and sore a few days before my period; I feel old and somewhat tired; For several days before my period I feel exhausted, lethargic or tired; The pain I have with my period is not intense but a continuous dull aching; I feel weak and dizzy during my period; I have abdominal pain or discomfort which begins one day before my period. |
| 2 | Academic Attitudes Toward Mathematics and Statistics | I don’t feel good being required to enroll in statistics; I hate buying a math textbook; I don’t like reading and interpreting graphs or charts; I don’t like being told how to interpret probability statements; I feel anxious watching a teacher work on an algebraic equation on the whiteboard; I feel restless listening to somebody explaining a math formula; I feel my chest pound when I walk into a math class. |
| 3 | Life Satisfaction and Outlook | I look back on my life, I am fairly well satisfied; I’ve gotten pretty much what I expected out of life; Compared to other people, I get more the share of bad luck; As I grow older, things seem better than I thought they would be; I would not change my life even if I could; Most of the things I do are boring or monotonous. |
| 4 | Perceptions of Aging and Physical Health | I feel old and somewhat tired; Most of the things I do are boring or monotonous; I feel my chest pound when I walk into a math class; I feel weak and dizzy during my period; I feel tired or lethargic. |
| 5 | Anxiety and Stress Related to Academic and Physical Conditions | I am anxious when I am waiting to get a math test returned even when I expect to have done well; I feel anxious watching a teacher work on an algebraic equation; I feel restless listening to somebody explaining a math formula. |
In sum, although these groupings are based on intuitive interpretation, they align with established psychological constructs such as physical symptomatology associated with menstrual cycles, attitudes towards academic pursuits, overall life satisfaction, perceptions of aging, and stress responses related to academic and physical challenges. This exercise underscores the importance of careful item analysis and theoretical grounding when hypothesizing about latent variables in psychological measurement.
