Expense Narrative [Text Block]	rr_ExpenseNarrativeTextBlock	This table describes the fees and expenses that are incurred, directly or indirectly, when a variable product owner buys, holds, or redeems an interest in an insurance company separate account that invests in the Series I shares of the Fund but does not represent the effect of any fees or other expenses assessed in connection with your variable product, and if it did, expenses would be higher.

Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 190% of the average value of its portfolio.

Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example does not represent the effect of any fees or other expenses assessed in connection with your variable product, and if it did, expenses would be higher. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies of the Fund
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in securities of U.S. issuers. The Fund deems an issuer to be a U.S. issuer if (i) its principal securities trading market (i.e., a U.S. stock exchange, NASDAQ or over-the-counter markets) is in the U.S.; (ii) alone or on a consolidated basis it derives 50% or more of its annual revenue from either goods produced, sales made or services performed in the U.S.; or (iii) it is organized under the laws of, or has a principal office in the U.S. The Fund invests primarily in equity securities of mid- and large- capitalization issuers. The principal type of equity security in which the Fund invests is common stock. The Fund invests primarily in securities that are considered by the Fund’s portfolio managers to have potential for earnings or revenue growth. The Fund may invest up to 20% of its net assets in securities of foreign issuers. The Adviser utilizes a bottom-up stock selection process designed to seek alpha (return on investments in excess of the Russell 1000® Growth Index), and a disciplined portfolio construction process designed to manage risk. To narrow the investment universe, the Adviser uses a holistic approach that emphasizes fundamental research and, to a lesser extent, includes quantitative analysis. The Adviser then closely examines company fundamentals including detailed modeling of all of a company’s financial statements, and discussions with company management teams, suppliers, distributors, competitors and customers. The Adviser utilizes a variety of valuation techniques based on the company in question, the industry in which the company operates, the stage of the business cycle, and other factors that best reflect a company’s value. The Adviser seeks to invest in companies with strong or improving fundamentals, attractive valuation relative to growth prospects and earning expectations that appear fair to conservative. The Adviser considers whether to sell a particular security when a company hits the price target, a company’s fundamentals deteriorate or the catalysts for growth are no longer present or reflected in the stock price. In attempting to meet its investment objective, the Fund engages in active and frequent trading of portfolio securities.
Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: Active Trading Risk. The Fund engages in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return. Foreign Securities Risk. The Fund’s foreign investments may be affected by changes in a foreign country’s exchange rates, political and social instability, changes in economic or taxation policies, difficulties when enforcing obligations, decreased liquidity, and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies. Growth Investing Risk. Growth stocks tend to be more expensive relative to their earnings or assets compared with other types of stock. As a result they tend to be more sensitive to changes in their earnings and can be more volatile. Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results. Market Risk. The prices of and the income generated by the Fund’s securities may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations. Mid-Capitalization Risk. Stocks of mid-sized companies tend to be more vulnerable to adverse developments in the above factors and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securities of mid-sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price.

Bar Chart and Performance Table [Heading]	rr_BarChartAndPerformanceTableHeading	Performance Information
Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The bar chart and performance table provide an indication of the risks of investing in the Fund. The bar chart shows changes in the performance of the Fund from year to year as of December 31. The performance table compares the Fund’s and the Van Kampen Life Investment Trust Capital Growth Portfolio’s (the predecessor Fund) performance to that of a broad-based securities market benchmark, a style specific benchmark and a peer group benchmark comprised of funds with investment objectives and strategies similar to those of the Fund. The bar chart and performance table below do not reflect charges assessed in connection with your variable product; if they did, the performance shown would be lower. The Fund’s and the predecessor fund’s past performance is not necessarily an indication of its future performance. The returns shown prior to June 1, 2010 are those of the Class I shares of the predecessor fund, which are not offered by the Fund. The predecessor fund was advised by Van Kampen Asset Management. The predecessor fund was reorganized into Series I shares of the Fund on June 1, 2010. Series I shares’ returns will be different from the predecessor fund as they have different expenses. All performance shown assumes the reinvestment of dividends and capital gains.

[1] The Adviser has contractually agreed, through at least June 30, 2014, to waive advisory fees and/or reimburse expenses of Series I shares to the extent necessary to limit Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement (excluding certain items discussed below) of Series I shares to 0.90% of average daily net assets. In determining the Adviser's obligation to waive advisory fees and/or reimburse expenses, the following expenses are not taken into account, and could cause the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement to exceed the numbers reflected above: (i) interest; (ii) taxes; (iii) dividend expense on short sales; (iv) extraordinary or non-routine items, including litigation expenses; and (v) expenses that the Fund has incurred but did not actually pay because of an expense offset arrangement. Unless the Board of Trustees and Invesco Advisers, Inc. mutually agree to amend or continue the fee waiver agreement, it will terminate on June 30, 2014.
